[preparation method of chelating mineral composition]
The technique and method that prepare foregoing chelating mineral composition are illustrated below.Fig. 1 is roughly to illustrate For the figure for the composition that the reactor for chelating mineral composition is prepared according to the exemplary embodiment of the present invention, Fig. 2 is general Slightly illustrate the precedence diagram for preparing the technique for chelating mineral composition according to the exemplary embodiment of the present invention.Simultaneously Reference picture 1 and Fig. 2, the method to the preparation chelating mineral composition of exemplary embodiment of the invention are illustrated.
As shown in figure 1, the reactor 1 of the chelating mineral composition for synthesizing the present invention can include:Raw material is put into Portion 10, air injection unit 20, reactant discharge unit 30, the stirring tool 40 of such as puddler, the alternative titanium dioxide being equipped with Carbon injection unit 50, temperature/pressure measurement portion 60, pressure-control valve (70).In fig. 1 it is illustrated that the composition of raw material throw-in part etc. It is provided to the situation of single-reactor, but it is also possible to use more than two reactors.For example, in first reactor, performing The reaction of organic ligand is extracted from carbonaceous material, in second reactor, the organic ligand and gold by means of extraction can be performed Belong to the reaction of raw material and generate the reaction of metallo-chelate.
On the other hand, as shown in Fig. 2 the method for preparing mineral matter mineral composition of the present invention can include:Prepare The step of carbonaceous material containing organic ligand (S210 steps);(S220 is walked the step of extracting organic ligand from carbonaceous material Suddenly);The step of being selectively generating calcium chelate compound (S230 steps);Input contains what can be reacted with the organic ligand The step of raw metal of metal ingredient (S240 steps);Optionally to the reactor for being mixed with organic ligand and raw metal The step of injecting carbon dioxide (S250 steps);Make the metal reaction that contains in organic ligand and raw metal and generate metal chelating The step of compound (S260 steps);And separated from the chelating mineral composition containing metallo-chelate, extract liquid phase and precipitation The step of thing (S270 steps).
First, the carbonaceous material of the raw material as organic ligand, made an addition to by raw material throw-in part 10 containing such as water Solvent reactor 1, prepare carbonaceous material (S210 steps).As it was previously stated, the carbonaceous material as organic ligand raw material can To be made up of the fertile soil containing humic substance, peat moss, peat, leonardite, lignite, asphalt carbon and combinations thereof Selected in group, wherein, the humic substance is the organic matter of such as humic acid, fulvic acid, ulmic acid and combinations thereof.It is preferred that Ground, as carbonaceous material, can select at least one in peat moss, peat, leonardite and lignite.
Preferably, before carbonaceous material devotes reactor 1, the pretreatment work for being ground into suitable size etc. can be performed Skill.For example, the carbonaceous material such as peat moss, peat, leonardite, lignite can be fed to crushing, part flow arrangement, it is suitable to be ground into Size is simultaneously shunted, dried.Now, carbonaceous particle is ground into reducing mechanism, wind or hot blast are supplied in reducing mechanism bottom, can Carbonaceous fraction (fraction) with carbonaceous particle only to dust form and with suitable size is shunted, and is supplied to reaction Device 1.It therefore, it can be processed into the mass transport process institute of the Extraction solvent in it may require that the separation type of accurate fraction or spoon type extractor It is required that carbonaceous material.
In an exemplary embodiment, devoting the carbonaceous of reactor 1 can use with average of 0.5 below ㎜ Grain size carbonaceous particle, for example, with mean particle size be 0.01 to 0.5 ㎜ carbonaceous particle, preferably use 0.05 to 0.5 ㎜ carbonaceous particle.If foregoing scope that the size of carbonaceous particle is not enough, although the extraction of organic ligand composition is held Easily, but there is the increased worry of processing charges of carbonaceous particle, if it exceeds foregoing scope, then needed for extracting organic ligand Reaction time can extend.
Then, organic ligand is extracted from the carbonaceous material, for example, the corruption such as extracted humic acid, fulvic acid and/or ulmic acid Grow material (S220 steps).In order to extract fulvic acid from carbonaceous material, special processing can not be required, but in order to extract humic Acid is, it is necessary to make the pH of reactant be changing into alkalescence.Therefore, can in reactor 1 be added suitably by raw material throw-in part 10 Basifier.
The basifier that can be used is not particularly limited, but basifier can by quick lime (CaO), calcium hydroxide (CaOH), Selected in the group that caustic soda (NaOH), caustic potash (KOH) and combinations thereof are constituted.By means of the processing of this basifier, The pH of reactor 1 containing carbonaceous material and solvent is transformed into alkaline state.In an exemplary embodiment, by means of adding Plus the alkaline agent, the pH of reactant can be adjusted to 8 to 12, preferably be adjusted to 8 to 10 or so.Therefore, the basifier can Reactor 1 is devoted with the concentration for pressing about 5~30% (w/v) in a solvent.
Basifier has optionally been put into, using stirring tool 40 to being dissolved with the carbonaceous of suitable particulate size in solvent The reactor 1 of material is stirred, and makes reactant more than 50 DEG C, for example, more than 80~100 DEG C of temperature and atmospheric pressure, example Such as under 1~2 air, react more than 12 hours, preferably react 24 hours to 72 hours.Therefore, contain in carbonaceous material Humic substance is dissolved in solvent with the form of organic ligand and is extracted by swelling.Now, the temperature and pressure of reactor can lead to Cross measurement portion (70) to measure, the air under atmospheric pressure can be for example injected inside reactor 1 by air injection unit 20.
By means of this processing, humic substance soluble in water is not only, even being used as the humic substance for being insoluble in water Macromolecule, also some hydrolyzable is into forms such as the humic acid, fulvic acid, ulmic acid of small molecule.Extract molecular weight it is small or The organic ligand of form soluble in water, this organic ligand can be extracted by reactant outlet 30.For example, conduct The humic acid of one of organic ligand contains a variety of anion, in the state of pH risings are alkalescence, with each of anionic property Molecule is mutually extruded, and carries out swelling while condensation is disintegrated in this way, becomes collagen phase, it is thus possible to which extracting these has Machine part.
On the other hand, fulvic acid is although soluble in water, but under the pH of acid condition, can be more soluble in water.In order to extract Fulvic acid, for example, can add acidulant in a solvent, and the acidulant can be the inorganic strong acid of such as nitric acid or hydrochloric acid, Or such as organic acid of lactic acid, acetic acid, fumaric acid, formic acid, propionic acid, malic acid, citric acid.For example, by means of adding these acid The pH of reactant, can be adjusted to 3~5 or so by agent.
According to an exemplary embodiment, in the humic substance contained in foregoing carbonaceous material, humic charcoal and acid Degree it is independently water insoluble, therefore, in other humic substances in addition, for example humic acid, fulvic acid, ulmic acid and they Combination in, at least one organic matter preferably selected in humic acid and fulvic acid is decomposed into organic ligand.
From the humic substance of carbonaceous material, according to color, the degree of polymerization, molecular weight, such as COOH bases/OH bases function Quantity, the quantity of carbon and oxygen, degree of exchange, water solubility of group (functional group) etc., can be divided into humic charcoal, humic Acid, fulvic acid, ulmic acid etc..These humic substances can make a distinction according to paradigmatic structure, ring/chain form etc., with substantially 5 ~50nm size, stereochemical structure and size are determined in humification process.
For example, humic acid is as being practically insoluble in water but by means of the alkaline agent of caustic potash (KOH), caustic soda (NaOH) etc. The high-molecular compound for handling and dissolving, with brown-dark brown, the functional group of intramolecular is more, thus various trace element appearances Easily combine, the part Nature District negative electrical charge of oxidation.Humic acid is intricately combined with ammonia as between aromatic ring and ring The complex aromatic race high-molecular compound (aromatic of base acid, amino sugar, peptide, aliphatic compound etc. Macromolecules), nitrogen, oxygen, hydroxyl, carboxyl etc. are diversely combined with aromatic rings.In humic acid organic structure, permitted Many part autoxidations and it is negatively charged.
Fulvic acid (Fulvic acid) is the high-molecular compound independently soluble in water with acidity, with yellow or Zhu Yellow.Fulvic acid has aromatic series, aliphatic structure, and two kinds of structures are widely replaced into containing aerobic functional group.Fulvic acid As the quantity of oxygen more than humic acid but carbon the quantity humic composition fewer than humic acid, largely contain functional group, it is particularly big Amount contains COOH bases, OH base C=O bases.
In a selective embodiment, the step of organic ligand is extracted in (S220 steps), can with it is foregoing Basifier together or independently of basifier adds gypsum (CaSO in reactor 14·nH2O).Gypsum is when generating phosphoric acid The trade waste of appearance, can be used as the presoma composition for constituting the metallo-chelate for chelating mineral composition of the invention And recycle.
If the organic ligand and gypsum of extraction are made an addition in solvent, due to gypsum the solubility of water is better than it is aftermentioned Raw metal, thus combined with the humic acid or fulvic acid as organic ligand etc., form calcium chelate.In the process, Free sulfuric acid and the metal salt or metal ion that are obtained from raw metal composition react, for example, and calcium carbonate reaction, become again Change calcium sulfate into, prevent that the pH of composition is low.The calcium sulfate of conversion can again with remove metallo-chelate form metal Remaining organic ligand reaction afterwards.
For example, the organic matter such as the humic acid contained in carbonaceous material, fulvic acid is huge macromolecular structure, central whole With by functional group is few, the low aromatic compound for being used as aliphatic acid and lignin of liposoluble constituent etc. to have phenyl ring of polarity Fat-soluble functional group formed by the influence of thing by representative of phenolic hydroxy group, and by the high water-soluble natural macromolecule of polarity Amino acid or sugar compounds influence formed by with the water-soluble function of alcoholic hydroxyl (ROH) and carboxyl (RCOOH) for representative Group.Therefore, these organic ligands due to cation exchange properties it is very high, thus the cationic various with periphery can be passed through The cation exchange reaction of material and generate chelate.
But, if gypsum, i.e. if calcium sulfate is excessive, be used as when the chelating mineral composition of the present invention During fertilizer etc., soil meeting acidification, the intake of animals and plants can become difficult.Therefore, gypsum is relative to carbonaceous material, substantially can be with Add, can preferably be added by 5~10 parts by weight ratios by 5~20 parts by weight ratios.
After suitable organic ligand is extracted from carbonaceous material, raw metal is devoted containing the organic ligand extracted Reactor (S240 steps).Raw metal is not particularly limited, and can contain such as sodium (Na), the alkali metal of potassium (K), such as magnesium (Mg), the alkaline-earth metal of calcium (Ca), the transiting metal component of iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), molybdenum (Mo) etc.. For example, raw metal can be selected in the group being made up of shell, shellfish fossil, mineral and combinations thereof.These raw metals With powder morphology or the block of suitable size can be truncated into put into.The raw metal of powder morphology can be preferably used, this When, raw metal can substantially have 0.1 to 2 ㎜ mean particle size.In the case where raw metal is with block use, its Size is not particularly limited, if for example using the calx of 0.5~20 ㎝ sizes, if preferably using 0.5~5 ㎝ sizes Raw metal, then having the advantages that being capable of high efficiency extraction metal ingredient.But, in the present invention, the size of raw metal is not What problem.
According to the present invention, compared with as the carbonaceous material of organic ligand raw material, offer and organic ligand knot is excessively added The raw metal of the metal ingredient of conjunction.Therefore, by means of organic ligand with from raw metal generate metal salt and/or metal from Son reaction and form metallo-chelate, meanwhile, include not with organic ligand react inorganic metal salt, such as metal ion And/or the inorganic metal compound of raw metal.Metal ingredient as metallo-chelate form is absorbed by organism, remaining Organic ligand can react with inorganic metal salt, metal ion and/or raw metal free in composition or remain again, weight Newly-generated new metallo-chelate.
In an exemplary embodiment, raw metal can be used for the carbonaceous material of organic ligand raw material excessively Addition.For example, raw metal is relative to carbonaceous material, can be by 1:1 to 10:1 weight, preferably can be by 1 than addition:1 to 5:1 weight is than addition.Therefore, the metal salt and/or a part for metal ion and organic ligand obtained from raw metal is anti- Answer and form metallo-chelate, but remainder can form the metal salt and/or metal ion of free state.Moreover, must In the case of wanting, a part for the metal ingredient that raw metal contains is transformed into free metal salt and/or metal salt, but a part Metal ingredient can be residued in raw metal.
Mineral as raw metal can be with the sulfide mineral containing foregoing metal ingredient, oxidation and/or hydrogen-oxygen Change inorganic acid mineral and combinations thereof that the forms such as mineral, carbonate, sulfate, silicate, phosphate contain metal ingredient. Can obtain suitable inorganic metal salt and/or metal ion from these raw metals, these inorganic metal salts and/or metal from Son can with the organic ligand of extraction directly in conjunction with.
As it was previously stated, the cation exchange capacity (CEC) of organic ligand is very outstanding.Therefore, in the embodiment of selectivity, In the state of generating calcium chelate using gypsum, by means of the inorganic metal salt and/or gold obtained from these raw metals Belong to the cation exchange reaction of ion and calcium chelate, the metal that can be obtained from inorganic metal salt is combined with organic ligand Metallo-chelate.
The inorganic metal salt obtained from raw metal is not particularly limited, as the species of inorganic metal salt, can by including The metal inorganic of the metal ingredient of foregoing raw metal sour (such as metal carbonate, phosphate metal or sulfuric acid metal), metal oxygen Compound, metal hydroxides, metal hydrate, metal sulfide, metal chloride and combinations thereof are constituted.In addition, metal Ion can be come from origin the sodium ion of raw metal, potassium ion, magnesium ion, calcium ion, iron ion, copper ion, zinc ion, Selected in the group that manganese ion, molybdenum ion and combinations thereof are constituted.
