Description

Detailed Description of the Invention

  The present invention is a production method in which a large amount of powdered calcium ions can be taken out by drying power clean ion water containing divalent calcium ions dissolved in an acidic aqueous solution and water. Calcium ions, which are usually used in powder form, can be mixed with water, but the amount of penetration is very small. The present invention is a production technique that not only removes heavy metals, but also enables a method of extracting calcium ions with high purity, as opposed to a method of dissolving a large amount of these in an acidic aqueous solution.

Current status of shell contamination and effective utilization of shells

  The background that led to the present invention is that there are a wide variety of shellfish that can be obtained in various parts of the world at present, but most of the shells after being edible are mostly discarded as waste in the sea or rivers. It is a cause of local environmental pollution due to dirt and bad smell. In addition, many shellfish are collected at the mouth of the sea or river, so they often coexist with industrial waste that flows into the sea or river. For this reason, the shells that can be taken there often contain heavy metals, and the effect makes the shellfish unusable and the range of use is limited. However, if heavy metals can be removed from shells, shellfish contain a large amount of calcium, so it can be used in a variety of ways, and it can be used in an unlimited number of applications. We know that when shells are baked at 1000 ° C to 1200 ° C, pure white calcium is obtained. However, as mentioned above, since a small amount of heavy metals and wastes are mixed, it is a problem to separate and extract only calcium ions, which must be solved.

The extraction of calcium ions from conventional shells is limited to those from carefully selected countries that do not contain heavy metals, and the method involves extraction of calcium ions by air drying after firing, but the price is high. The problem is that the amount of extraction is small. Most of the other shells contain very small amounts of heavy metals, so their use is very limited and most are destined to be bird food or thrown away without being used.
Therefore, until now, the method of extracting the calcium ions by dissolving the shell in an aqueous solution is untouched.

Basic philosophy of invention

Here, an example is shown in which acetic acid is used as the acidic solution and granular calcium produced by firing shells is used as the calcium raw material.
First, water is put into a container, and an acidic solution is added thereto to form an acidic aqueous solution. Then, granular calcium is added to the aqueous solution, and when sodium hydrogen carbonate is added and reacted, carbon dioxide gas is generated. The carbonate inside is decomposed and divalent calcium ions are dissolved in the aqueous solution. Since the dissolved calcium ions need to be separated and removed from heavy metals and wastes contained in the solution, if the aqueous solution is left to stand for several hours, they precipitate and accumulate on the bottom. This is a production method in which an aqueous supernatant solution is extracted from the sediment layer accumulated at the bottom, and when the extracted solution is passed through a filtration device, colorless and transparent power clean ionic water is obtained.
This power clean ionized water removes mold and stubborn dirt (weakly acidic aqueous solution) such as tombstones, cars, bathrooms, etc. that are contaminated with scales, depending on the concentration (range from weakly acidic to neutral). In addition, it has the characteristic of finishing (neutral aqueous solution). This is due to the synergistic effect of calcium ions and weak acids. Compared to conventional stain removal, power clean ionic water is harmless to the human body.

Power clean ion water production method

The production method of the present invention will be described with respect to the acidic solution shown below. The same applies to other acidic solutions.
(1) Acidic solution (acetic acid): 1000 cc, water: 1000 cc, granular calcium: 200 g, sodium bicarbonate: 30 g
(2) First, 1000 cc of an acidic solution (acetic acid) is added to 1000 cc of water and stirred well to make an acidic aqueous solution.
(3) After adding 200 g of granular calcium to this acidic aqueous solution and stirring well, sodium bicarbonate is added little by little while observing the reaction state and allowed to react for about 5 hours.
As a result, the granular calcium is decomposed from the carbonate while forming small bubbles in the acidic aqueous solution by the action of carbon dioxide gas made from sodium hydrogen carbonate, and dissolves in the aqueous solution as divalent calcium ions.
(4) An acidic aqueous solution containing divalent calcium ions is a weak acid, so it has an odor peculiar to acetic acid, but it must be removed, and by adding sodium hydrogen carbonate, the aqueous solution becomes neutral (pH : 7) Close and dilute with water to make it neutral.
(5) In order to precipitate unnecessary substances and heavy metals in the neutralized aqueous solution, leave it for a few hours, remove the precipitated unnecessary substances, and put the supernatant in a filtration device and filter it. Clean ionic water is obtained.

Analysis results and discussion

  The analysis results of the power clean ion water solution are shown in FIGS. FIG. 1 shows the analysis result of the acidic aqueous solution. 2 to 6 show changes in pH and calcium penetration when adding powdered calcium and granular calcium obtained by examining fluorescent X-ray spectra of water and acidic aqueous solution.

(1) As can be seen from FIG. 1, it can be seen that the amount of calcium ions dissolved in the power clean ion water is very large compared to other elements. It can also be seen that the ionic water does not contain heavy metals.
(2) FIG. 2 is a calibration curve of fluorescent X-ray spectrum when calcium is dissolved in water, and FIGS. 3 to 6 are calibration curves of fluorescent X-ray spectrum of acidic aqueous solution (acetic acid, citric acid, formic acid, tartaric acid). It is. According to this, when calcium dissolves in water, 16.9 g of calcium is in 1 liter of water.
In contrast, in the case of an acidic aqueous solution, acetic acid is 44 g, formic acid is 24 g, citric acid is 21 g, and tartaric acid is 2.9 g. In this acidic aqueous solution, acetic acid has the strongest ability to dissolve calcium. It is optimal as an acidic solution for power clean ion water production.
(3) FIGS. 7 to 9 show changes in pH when PH and calcium are mixed with acidic solution concentrations (acetic acid, citric acid, tartaric acid) and how much calcium dissolves in the acidic solution. Is.
According to this, it can be seen that when the aqueous acetic acid solution contains calcium ions, the pH is 6.5 to 4.6 compared with other acidic aqueous solutions, indicating weak acidity. It was also found that the amount of penetration increased rapidly as the acetic acid concentration increased.
From the above (1), (2) and (3), it is understood that calcium ions are dissolved and exist as ions when granular calcium prepared by baking shellfish in an acidic aqueous solution is added. Among these acidic aqueous solutions, especially the acetic acid aqueous solution has the property of penetrating calcium ions very much, and further, the acidic concentration is from weakly acidic to neutral, and is an optimal solution for the production of power clean ionic water of the present invention. It is.

Claims (3)

  Water is put into a container, and an acidic solution is added thereto to form an acidic aqueous solution. In the acidic aqueous solution, a shell forked at 1000 ° C. to 1200 ° C. or calcium carbonate taken from limestone is added, and further, the aqueous solution is added. When sodium hydrogen carbonate is added and reacted, carbon dioxide is generated, and the carbonate in the acidic aqueous solution is decomposed by the carbon dioxide and divalent calcium ions are dissolved. Calcium ions dissolved in the acidic aqueous solution are separated and removed from heavy metals and wastes contained in the solution, so if the acidic aqueous solution is left for several hours, they precipitate and accumulate on the bottom. When the supernatant aqueous solution is taken out from the sediment layer accumulated at the bottom and passed through a filtration device, colorless and transparent power clean ion water is obtained. That is, the scope of the claims is the above-described production method using all the shells, limestones, etc. containing the acidic aqueous solution and calcium necessary for producing power clean ion water.   The power clean ion water described above contains a large amount of calcium ions in an acidic aqueous solution, but heavy metals cannot be removed simply by dissolving the baked shellfish in the acidic aqueous solution. When this aqueous solution is allowed to settle for several hours, impurities containing heavy metals settle on the bottom of the container, and the supernatant above the portion that has settled on the bottom is taken out to separate heavy metals and power clean ion water. Since the power clean ionic water that has been taken out contains a large amount of calcium ions, when this power clean ionic water is placed in a metal pan etc. and dried by heating, 100% pure white calcium ion is obtained. Production method to produce.
