Abstract

PURPOSE:To obtain an antiseptic having an excellent sterilizing and bacteriostatic power and making water slightly alkaline by activating a sandy coral fossil without salinity by heating under reduced pressure, coating a prescribed amt. of gold on the activated fossil. CONSTITUTION:Granular coral fossils or coral sand are desalted by washing with water and activated by heating at 200-1,000 deg.C under reduced pressure for about 20-120min preferably in the presence of an inert gas to decompose the adherent organic components. Then the activated material is dipped in a water soluble salt of tetrachlorauric acid or the like to sufficiently adsorb the salt, then reduced by adding a reducing material such as grape sugar. The resultant is dried at 100-200 deg.C, fully washed with water, and kept at 50-80 deg.C for about 3-5hr. The weight of gold to be coated is regulated to <=10%, preferably 0.1- 5%.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention exhibits a sterilizing or bacteriostatic effect by immersing it in water such as drinking water, prevents the water from spoiling, and makes the water slightly alkaline, producing high-quality mineral water. Regarding preservatives for drinking water, etc., the purpose is to sterilize purified water and remove limescale odor. Conventionally, activated carbon, activated carbon with silver attached to it, or pH caused by residual chlorine in tap water
In order to prevent the decrease in oxidation, purifying agents that use calcium carbonate in combination have been proposed. Calcium carbonate needs to be highly purified in order to remove harmful metals, and activated carbon has disadvantages such as its excellent adsorption ability, which quickly reaches saturation and has a short lifespan as a water purifying agent. It did not become widely popular.

The present invention was made in view of this problem, and focused on naturally produced coral fossils or coral sand that can be obtained at low cost.
By coating this with gold, which has relatively strong sterilization and bacteriostatic power compared to the silver, it has excellent sterilization and bacteriostatic power, and also makes the water slightly alkaline, making it a high-quality mineral water. The purpose is to provide a preservative that can

Next, to explain one embodiment of the present invention, granular coral fossils (or coral sand) are desalinated by washing with water, and then desalinated under reduced pressure, preferably in the presence of an inert gas, for 20 to 120 minutes.
It is heated to 200 to 1000°C to activate it, decompose the attached organic components, activate the pores of the coral fossil, and coat it with gold.

This gold coating is made by immersing a coral fossil in a water-soluble salt such as tetrachloroauric acid to adsorb and retain the water-soluble salt inside the pores and on the external surface of the coral fossil, then adding a reducing agent such as glucose and heating. , give back. After reduction, 100-200
Dry at °C. As a result, water-soluble salts such as tetrachlorometallic acid deposited and retained on the surface or internal surface of the coral fossil are reduced to metallic gold. Next, the product is thoroughly washed with water until water-soluble salts such as tetrachloroauric acid are no longer detected, and finally dried by holding at 50 to 80°C for 3 to 5 hours to obtain a product. Gold to coat coral fossils is 10 by weight.
It is preferably within the range of 0.1 to 5%. If the weight of the coated gold exceeds 10 parts, the layer of metallic gold covering the coral fossil will become too thick, and the main component of calcium carbonate and trace components of potassium, magnesium, phosphorus, and manganese will be removed. , the elution of active ingredients such as copper and iron is hindered. When the preservative thus obtained is poured into tap water, the gold attached to the coral fossils gradually dissolves into gold ions, exerting a bactericidal effect. That is, gold is harmless to the human body at a concentration of 14 ppb or less, and is contained in the human body at a concentration of 141)I)b or less.

On the other hand, coral fossils whose main component is calcium carbonate (

(5) As a result, the slightly acidic tap water containing chlorine with a limescale odor is neutralized and deodorized, becoming slightly alkaline, and is sterilized by the generator's oxygen O↑. Moreover, mineral ions useful for the human body such as calcium ions (C, `` '') and trace components such as magnesium, potassium, copper, iron, and manganese are eluted, resulting in delicious mineral water.

Next, the above preservative was placed in water and stored for one year, and the results are shown in the following table in comparison with the water quality standards of the Water Supply Act.

As described above, the present invention is a preservative in which 0.1 to 10% gold is attached to sandy coral fossil or coral sand that is substantially salt-free and heated under reduced pressure to activate it. , gold ions are generated in the water to sterilize or bacteriostatic, the water will not spoil even if stored for a long time, and the deodorizing effect eliminates the smell of metal, and it is a weak alkaline IJ.
A high-quality mineral water containing calcium and other cations can be obtained by using i.

Furthermore, since coral fossils that serve as raw materials are naturally produced and can be obtained at low cost, it is possible to provide a preservative that is generally much cheaper than conventional preservatives, has a long lifespan, and is easy to use.
