Description

Method of analyzing, identifying, detecting, developing and using complex compounds of peculiar components and natural fertilizers using the characteristics and ingredients of phosphate stones And natural fertilizer materials containing specific elements urea {The method that uses the mineral Phosphoniter on the analysis, discerns, detects, develops, for the mineral Phosphoniter the complex compound of the peculiar components, and the natural fertilizer that utilizes peculiarity, and the components, the mineral Phosphoniter, and the mineral Phosphoniter of the natural fertilizer material that contains the peculiar component element.}

The fertilizer new material phosphate stone provided by the present invention is indistinguishable from limestone 〈CaCO ₃ 〉 and can be identified by professional technicians and is equal to the calcium carbonate 〈CaCO ₃ 〉 diffraction value in the X-ray powder diffractometers (X, R, D). The 8-hour calcining loss of ore at 900 ° C also has a 36% reduction rate, such as calcium carbonate <CaCO ₃ >, so the mineral institute's theory says that it cannot be other than limestone based on the theory of mass conservation. I).

Phosphorus and nitrogen are not detected by other sample preparation methods, but more than 0.03% of phosphoric acid and more than 0.3% of nitrogen can be detected by other methods. The calcined lime <CaO>, which calcined the ore at 900 ° C for 8 hours, was changed to red because it could not be understood as the color of slaked lime. As a result of requesting the natural and mineral emotion, no other components were detected except the limestone component, and the mineral emotion was also the result of the limestone mixed with dolomite.

Even in this analysis, the inventors could not understand the calcined red matter as limestone, and began to conduct an experimental study to find out through direct physicochemical experiments. The red matter is elemental phosphorus (P) and the ore is not limestone. , A new phosphate.

Phosphorus dissolves in the rock, part of it enters the soil, is absorbed by the plant, and then enters the plant from the animal's body, through the animal's feces and bones, whereby the carcasses of the organisms are decomposed and re-dissolved to reach the sea It is accumulated or settled by the living organisms to form a sedimentary layer, and it is returned to the land as an uplift to create a large phosphorus deposit. The phosphorus deposit thus produced is called an organic phosphorus deposit and occupies 80% of the world's production, and many ores are mixed in this ore.

This change of mineral deposits such as magma intrusion due to the earth's crust is a change of minerals that is adapted to environmental changes by forming a stable new form of chemical equilibrium under the changed conditions of rocks and minerals. .

Inchoseok is also a seabed sedimentary rock, and is a seabed sedimentary organic phosphorous deposit, and traces of magma ignition activity such as igneous penetration and fold formation around the deposit are observed. As organic matter is rare in the ore, the organic substance is lost due to heat denaturation and the transition metamorphism to inorganic compound is arranged as the cause of the formation of specific isomer phosphate stone. Be established.

In phosphate stone, cyanamide (CN ₂ ^-2 ), which is not present in the conventional phosphorus ore, is involved in the crystal compound structure to generate complex isomeric compounds. The formation of these inorganic compounds is possible only under pressure conditions deficient in thermal energy and oxygen, and it is believed that the action is due to the formation and uplift of geologically magmatic activity. .

The chemical structural formula of phosphate is → <[Ca ₅ (PO ₄ , CN ₂ ) ₃ ] 3OH>

The complex component of phosphate is composed of a poly nuclear complex peculiar isomer complex in which calcium, phosphorus, nitrogen, carbon, and oxygen molecules are formed by intermolecular bonds. Because of different physicochemical properties, the target components could not be detected by any physicochemical method.

To convert complex compound of phosphate stone into Ortho Phosphoric acid, dry it with inorganic solvent 〈H ₂ SO ₄ , HCl, HNO ₃ , HClO ₄ 〉 and add another solvent and addition compound. Samples may explode immediately before drying when complex ions are produced and are not dry with recrystallized salts and try to dry and dry a very complex new complex ionization sample.

When calcite is calcined at 900 ° C in calcination, the reduction ratio of plasticity is reduced from 33% to 43% according to the minor component crisis (oxidation reduction).

Complex compounds are not easily decomposed by ionization in solvents, but are easily decomposed in heat, and each element is oxidized or reduced by automatic redox reactions, and some of the elements are volatilized. By comparing the mass ratio of the residual components and the volatilization mass ratios in the mass of the component molecules calcined and decomposed in the following scheme, the cause of the plastic loss can be known.

When pyrolysis of phosphate is distinguished from residual and volatilized components and the oxidized and reduced components in the oxidized and reduced molecular mixtures, it is possible to know what kind of component is a fired red substance.

It is not easy to quantitatively detect the phosphoric acid component by converting a phosphate complex compound having such a structure into a reagent and an inorganic solvent with a phosphate ion <PO 4 ^3- > furnace sample.

Phosphate is the causative agent of complex-specific isomer formation with cyanamide <H ₂ CN ₂ > te nitrogen. The material hydrolyzes at neutral and slightly acidic room temperature to produce ammonia and carbonate <H ₂ CO ₃ >. The reaction formula is <H ₂ CN ₂ + 5H ₂ O = H ₂ CO ₃ + 2NH ₃ OH>

Cyanamide 〈H ₂ CN ₂ H ₂ O〉 decomposes in a strong acid solvent and reacts with a strongly reducing substance, thereby reducing the phosphorus component of phosphate to low phosphate or elemental phosphate to reduce the phosphoric acid content in phosphate stone to oxygenate Interferes with deodorizing molecules.

By forming cyanamide involved in phosphate stone as a safe ionizing aqueous solution with potassium cyanamide <K ₂ CN ₂ , H ₂ O> to inhibit complex ionization, by forming phosphoric acid as regular phosphate ion <PO ₄ ^3- > Phosphoric acid component could be detected. The method is explained in the following example. In this way, it is possible to detect 15-20% of the soluble phosphate <P ₂ O ₅ > contained in the phosphate stone, and the quantitative method was applied to ammonium vanadium molybdate absorbance method.

The quantitative method is a phosphate quantitative method using a physicochemical method is a cumbersome but accurate analysis of the sample composition and reagent preparation is used mainly for fertilizer inspection.

In order to quantify phosphate stone with an analyzer (ICP), the sample should be prepared by forward phosphorylation and analyzed by a solution of phosphorus molybdate and ammonium yellow precipitate dissolved in filtered ammonia water.

The analytical method provided by the present invention is a core technology for analyzing, identifying, exploring, developing, and utilizing the characteristic components of phospholipid, and can mass-produce highly efficient, eco-friendly natural fertilizer without chemical plants by utilizing the characteristic components of phosphite stone. It was made.

The new fertilizer, which is a beneficial material and ingredient for plant nutrition, has no impurities or harmful components. Natural fertilizer produced in mass production only by physical processing (grinding process) is a spherical natural synthetic fertilizer that is completely different from the artificial synthetic structure of chemical fertilizer.

Natural fertilizer produced from phosphate stone is not water-soluble, but it is a water-soluble fertilizer, which is beneficial for plant nutrition. The long-term supply of plant inorganic nutrients to the soil, while remaining fertilizers completely solve the problems such as soil acidification and soil fixation. Solved.

Natural fertilizers can be cultivated without fertilizer fertilization for three to five years with one fertilization by continuously supplying plant nutrition while preserving the soil environment, which can be called a groundbreaking fertilizer, which can greatly reduce the amount of fertilizer used while increasing agricultural productivity.

Natural fertilizer produced from phosphate stone is highly regarded as a high-efficiency, environmentally-friendly and resource-saving plant-nutritional complete fertilizer due to the 90% dissolution of citric acid in minerals containing large amounts of inorganic nutrients in plants. . If these characteristics are lacking, phosphate rock is no different from conventional phosphate ore, a chemical fertilizer.

The chemical structure of the conventional phosphate ore is 〈Ca ₁₀ (PO ₄ ) ₆ F _2-6 〉 a higher order compound phosphate and the insoluble ore itself, which has a very stable structure, cannot be used as a fertilizer.

Phosphorous fertilizer production method in chemical fertilizer plant imports raw materials ore (1 million tons per year) and grinds sulfuric acid solvent to dissolve ore and re-crystallize insoluble ore phosphate primary calcium phosphate phosphate lime <Ca (H ₂ PO ₄ ) ₂ + ₂ CaSO ₄ > fertilizers and phosphorus ores extracted from phosphoric acid, ammonium diammonium phosphate <(NH ₄ ) ₂ HPO ₄ > chemical compound fertilizer is produced and produced.

Soluble ratio 〈CaO · 2MgO · P ₂ O ₅ · 2CaSiO ₃ · 3MgO · P ₂ O ₅ · 3CaSiO ₃ 〉 was mixed with phosphorus ore and serpentine, melted at 1300∼1400 ℃ in an electric furnace, quenched with water and dried Old-soluble phosphate fertilizer is produced, but there are problems in production cost and mass production. There are many other types of chemical phosphorus fertilizers, but the above-mentioned fertilizers are representative chemically manufactured phosphate fertilizers.

Phosphate fertilizers produced in this way are highly regarded for increasing agricultural productivity and contributing to food production. However, excessive use of chemical fertilizers leads to agricultural land degradation and salt degradation. In the manufacturing process, it is said that phosphoric acid is extracted and industrial wastes of the production by-product calcium sulfate <CaSO ₄ > are not recycled and there is no way to be treated.

The other problem with chemical fertilizers is that the absorption of used fertilizer is about 20%, and the remaining fertilizer is waste of resources because the soil cannot be reabsorbed by soil immobilization (insolubilization) after a certain period of time (within one year). And economic loss is in serious shape.

Chemical formula of phosphate fertilizer +

1,942 tonnes of water-soluble superphosphate fertilizers are produced with 183 tonnes of sulfuric acid (69.2%) on one tonne of insoluble phosphate. Other fertilizers are also water-soluble.

Sodium phosphate fertilizer is 94% calcium sulfate, soil acidification cause material, fertilizer component water-soluble lime phosphate monocalcium phosphate, unstable compound is soil metal oxide due to the nature of chemical equilibrium reaction to return to a safe state Is substituted with adsorbed hydrogen molecules to produce insoluble triphosphate salts.

As an alternative to solve the problems of phosphate fertilizer, polymerized phosphate 〈M ₅ P ₃ O ₅ 〉 was developed, but it delayed soil immobilization but not completely solved fertilizer, and it did not lead to commercialization due to technical problems in expensive production cost and mass production. It is said.

Nitrogen fertilizer for chemical production is the liquefaction and separation of molecular nitrogen in the air to form ammonium salt 〈(NH ₄ ) ₂ SO ₄ , (NH ₄ ) ₂ PO ₄ 〉 nitrate 〈MNO ₃ 〉 an organic compound, urea 〈CO (NH ₂ ) ₂ 〉 calcium cyanide Although there are many kinds of synthetic nitrogen fertilizers such as amide <CaCN ₂ >, all of them are water soluble in the problem, and the rate of use of the fertilizer absorbed by plants is 30 to 60%. As a solution to this problem, poorly soluble fertilizers have been developed, but fully-soluble fertilizers have not been developed until now.

Mineral Nitrogen Fertilizer, KNO ₃ produced in Chile at the end of the 19th century, is the most water-soluble, which is most limited in the dry desert area. It has been used in fertilizer and nitric acid industry. Guano) is a result of the accumulation of seaweed powder, etc., which was produced in Peru using 10-12% of nitrogen and phosphoric acid as natural fertilizers, but guano is not a mineral but an organic compound. .

Phosphate has no added mineral acid, so it does not provide soil acidification material, and it is completely soluble, not water soluble, solubility in cetal plants lost in water, no nutrient over-absorption disorders, and completely solves soil immobilization, the most important problem of chemical fertilizer. It is a complete fertilizer of phytonutrients that saves money and preserves the agricultural environment.

As a reliable basis for this function and action, geological formation of geological deposits occurred over 1 billion years ago at the bottom of the sea. So far, 90% of inorganic compounds have been stabilized at room temperature. This is because the chemical principle demonstrates that there is no change in chemical production in the natural environment.

Qualitative quantitative analysis method according to the present invention is an essential method for the analysis and development of the characteristics of phosphate stones and the identification of phosphate stones.

It is the analysis of the content of the target ingredient as an essential condition for the process of obtaining the legal license for the process of identifying and developing new fertilizers, which are provided through such methods, and developing natural fertilizers.

Mining registration, mining permits, fertilizer process standards, and fertilizer production registration are the legal conditions that must be obtained by fertilizer producers specified in the Mining Law and the Fertilizer Control Act.

The phosphorus permit is a legal condition that must be obtained for the production and sale of phosphate stone for the prospecting development of natural fertilizer. Even without the permit, even if the phosphate stone is highly effective and pollution-free, it is impossible to supply fertilizer. .

Considering these legal situation conditions, the analysis method of phosphate stone provided by the present invention is a core technology for producing and utilizing phosphate stone to produce and use natural fertilizer.

Example 1.Method of soluble phosphate assay contained in phosphate stone

Take 0.2 g of phosphate powder sample in a 250 ml volumetric flask, add 100 ml of 2% citric acid <C ₆ H ₈ O ₇ H ₂ O> solution, shake it for 3 hours with a shaker (keep it at 30 ℃), and then put it in a 300 ml beaker. Transfer and filter, wash the filter paper eight times with 100 ml of distilled water and discard the filter paper. Put 200 ml of the filtrate, add ₄ g of reagent potassium chlorate 〈KClO ₃ 〉 and 20 ml of concentrated nitric acid 〈HNO ₃ 〉, stir and dissolve with a glass rod, and cut off. At a concentration of 20-25 ml, the solution is placed at 100 ml mark with cold distilled water and quantitatively determined as ammonium vanadium molybdate absorbance. (The colorant uses B colorant.)

<Expected concentration of phosphoric acid (P ₂ O ₅ ) in 10 ml of fixed solution is 10 ml / 4 mg.>

By the above analysis method, it was possible to detect 15-20% by weight of the soluble phosphate &lt; P ₂ O ₅ &gt;

Citric acid dissolution of the sample is a fertilizer assay, soluble phosphate content assay, and other solvents may be used to quantify the total amount of phosphate. The difference from the conventional fertilizer analysis method is that the operation of concentration up to 25 ~ 30ml differs by using excess potassium chlorate and adding nitric acid.

Conventional phosphate ore analysis methods have made analytical methods based on the physicochemical properties of phosphate, and the standard sample and instrumental line (Wavelength (nm)) also have Ortho Phosphoric acid. The component phosphoric acid could not be detected by preparing and quantifying the sample by the analytical method.

Example 2. Method of quantifying the total amount of nitrogen (N) contained in phosphate stone (distillation method)

0.4 g of phosphate powder sample was placed in a 200 ml beaker, 10 ml of concentrated hydrochloric acid (HCl) was added thereto, and evaporated to dryness at room temperature. 100 ml of saturated sodium hydroxide (Na OH, H ₂ O) was added to the dried sample and mixed with the sample. Next, transfer to a distillation flask, a standard sulfuric acid solution is connected to the distillation apparatus, and 100 ml of 30% hydrogen peroxide is distilled while adding 5 ml of distillation flask. After distilling until 100 ml of hydrogen peroxide is used up, when the bubble is weakened, it is heated and distilled until the contents are drained out by about 2/3. After washing the tip of the induction pipe with water, add 1-2 drops of indicator methyl red to the effluent. Titrate nitrogen with sodium hydroxide solution. The difference from the conventional nitrogen analysis method is that the sample is dried and dissolved in hydrochloric acid and distilled with 30% hydrogen peroxide added.

(1 ml of standard sodium hydroxide solution corresponds to 0.0014 g nitrogen (N).)

The analysis method can detect the weight ratio 12-15% of the nitrogen component contained in phosphate stone.

The analytical method is a representative specific example and is not limited thereto. Sample soluble solvents may be varied but the use of excess strong oxidants is essential.

Obviously, the conventional analytical sample preparation method cannot detect the phosphorus nitrogen contained in phosphate stone by any physicochemical analysis method.

Example 3 Characteristic Chemical Reaction Experiment of Phosphate Stone

Put phosphate stone in a magnetic crucible and cover it with a cover and heat treatment at 900 ℃ for 8 hours to see the red material, and after 24 hours heat treatment, you can see black material. When concentrated hydrochloric acid <HCl> is added to the red substance, it smells like fish rotting. The gas of that smell is hydrogen phosphide (PH ₃ ).

<Scheme (1): 5CaO, (PN) ₃ + 10HCl = 5Ca (Cl) ₂ → N ₂ O ₃ + NO ₂ + 3PH ₃ > When the calcined material is diluted with water for 24 hours, the liquidity is alkaline and diluted with hydrochloric acid. Little by little, black matter precipitates in neutral. The black material is black (3P ₄ ).

<Scheme (2): 5CaO, (P ₄ ) ₃ + 50H ₂ O + 10HCl = 5Ca (Cl) ₂ + 50H ₂ O → 3P ₄ >

The cause of this physical change of phosphate stone is based on the complex compound. Coordination between the central atom and the coordinating compound of the coordination compound is a complex compound having weak binding stability due to covalent bonds, and is easily decomposed by heat to change into a molecular mixture.

<Scheme (3): [Ca ₅ (PO ₄ , CN ₂ ) ₃ ] 3OH = 5CaO + (PN) ₃ → 3CO ₂ , + NH ₃ + N ₂ O ₄ >

Example 4 Characteristic Chemical Reaction Experiments of Pharyngite

Approximately 1 g of phosphate powder sample is taken in a 200 ml beaker, dissolved in 20 ml of concentrated hydrochloric acid <HCl>, the residue is discarded, evaporated to dryness, and the sample turns red. When 50 ml of distilled water is added and left alone, red salt precipitates. <Scheme (4): [Ca ₅ (PO ₄ , CN ₂ ) ₃ ] ₃ OH + 10 HCl = 5Ca (Cl) ₂ + (PN ₂ ) ₃ + 6H ₂ O> The precipitated red substance is phosphorus nitride (PN ₂ ) ₃ . After dissolving and drying the existing phosphorus ore in hydrochloric acid, the hydrochloric acid solvent is volatilized and phosphorus ore is recrystallized from tricalcium phosphate salt. This is because the conventional phosphorus ore is ortho phosphate (Scheme (5): Ca ₁₀ (PO ₄ ) ₆ F ₂ + 20HCl → 10Ca (Cl) ₂ + 6H ₃ PO ₄ + H ₂ F ₂ → 3Ca ₃ ( PO ₄ ) ₂ + CaF ₂ → 20HCl> In the above experiments, the same experimental results can be seen with aqua regia and nitric acid in addition to hydrochloric acid.

Example 5 Qualitative Analysis of Nitrogen Contained in Phosphate

Take 1 g of phosphate powder sample into a 250 ml beaker, add 10 ml of concentrated hydrochloric acid (HCl), and heat evaporated to dryness to room temperature. Add 100 ml of saturated sodium hydroxide (NaOH, H ₂ O) solution, stir and mix well with the sample 5-10 ml of 30% hydrogen peroxide 〈H ₂ O ₂ 〉. When bubbles are generated, wet the red litmus broth with water and place it at the inlet of the flask. Wait for a while. Nitrogen content can be confirmed by qualitative analysis.

<Scheme (6): 5Ca (Cl) ₂ , (P = N ₂ ) ₃ , 6NaOH, 6H ₂ O + 3H ₂ O ₂ = 5Ca (Cl) ₂ + 3Na ₃ PO ₄ → 6NH ₂ >

Example 6 Qualitative Analysis of Phosphoric Acid Contained in Phosphate

To 1 g of phosphate powder, mix 3 g of ammonium molybdate <(NH ₄ ) ₂ MoO ₄ and 1 g of ammonium nitrate (<NH ₄ NO ₃ > 1 g) into a 200 ml beaker and add 40 ml of concentrated nitric acid <HNO 3> for 30 minutes. If you wait, the sample dissolves and turns yellow, and the reagent reacts with phosphoric acid, which is the phosphate reaction contained in the phosphate stone.

Scheme (7): 〈[Ca ₅ (PO ₄ , CN ₂ ) ₃ ] 3OH + 18 (HN ₄ ) ₂ MoO ₄ + 3NH ₄ NO ₃ + 34HNO ₃ = 3 (HN ₄ ) ₂ HPO ₄ 6MoO ₃ → 5Ca (NO ₃ ) ₂ + 24HN ₄ NO ₃ +3 (NH ₄ ) ₂ CN ₂ + 18H ₂ O>

Change in soil fertilizer content and acidity of crops Experimental soil [Fig. 1, 5] In the test results table, the fertilizer has no change in soil acidity, so it is confirmed as pollution-free. .

Example 8. Result report of requesting analysis of phosphate stone to another analysis laboratory.

Phosphoric acid detection amount in the component analysis of phosphate stone in the above notation is the phosphate content value contained in the general soil, and the characteristic component phosphoric acid of phosphate stone was not detected. This is because phosphate stone is a new mineral containing specific components, and these phosphate compounds do not have an analytical sample preparation method.

When qualitatively, quantitatively and analyzing the phosphorus (P) component of phosphate stone by physical device analysis (ICP), the matrix material of the sample should be removed. When phosphate is dissolved in a solvent, its constituent elements generate new complex ions with the solvent, which interferes with the interference ionization of the analyte (P) in the plasma.

The history of agriculture can be said to be a record of efforts to increase food supply by increasing the supply of solar powder. Fertilizer is, in a broad sense, all the restraint provided to the soil to supply the elements necessary for plant growth.

In order to achieve this goal, science and technology made artificial chemical fertilizers and contributed to food production, but the side effects are leading to degradation of farmland. Nowadays, science and technology has advanced to the extreme, but it does not solve the problem of chemical fertilizers.

The analysis, identification, exploration, development, utilization, and method of natural fertilizer material phosphate stone provided by the present invention is an essential method for producing natural fertilizers that provide high-cost and low-cost agricultural production from pollution to clean agriculture.

Natural fertilizers provided through this method enable mass production of environmentally friendly fertilizers only by mining ore without a chemical plant.

Phosphate is not water-soluble but is water-soluble, so it is easy to pack, store and manage, and it completely solves the problems of chemical phosphate fertilizers such as soil acidification and soil immobilization (insolubilization), which is a problem of chemical fertilizers which improves agricultural productivity while preserving agricultural environment.

The chemical nitrogen fertilizers are all water-soluble, the most important problem is the loss of cetal in rain water. It is more soluble than water soluble because it is the most ideal method of feeding plant phytonutrients by keeping the fertilizers in the soil for a long time and dissolving and absorbing organic acids from the root as needed.

As a solution to these problems, research efforts have been made to reduce the number of fertilizers and environmental pollution by applying water-soluble fertilizers with paraffin and rosin to the surface of fertilizers to inhibit the penetration of water, making them poorly soluble and remaining in the soil for a longer time. have.
