<p>PURPOSE:To improve the activity of aerobic microbes efficiently and to perform purification easily and inexpensively by spraying a metallic colloidal soln. prepd. by adding a very small amts. of specific metallic salts to iron compounds and further adding a polymer material as a stabilizer thereto to a material to be purified. CONSTITUTION:A small amt. of a polymer material as a stabilizer is added to a colloidal soln. consisting essentially of iron compound and a very small amt. of metallic salts of Na, Ca, Mg, copper, Al, etc. whereby a metallic colloidal soln. is prepd. This soln. is sprayed on a material to be purified such as soil, water, atmosphere or the like. The metallic colloidal soln. is prepd. by adding water at about 20 ratio to about 5 the mixed powders compounded with about 80-85% iron sulfate contg., for example, bivalent and trivalent irons and about 15-20% other metallic salts to prepare a metallic colloidal soln., then mixing a highly hydrophilic polymer material therewith and deluting the mixture about 100-200 times.</p> |
