Методика

One hundred grams of black iron oxide was added to 400 ml of water and mixed using a home type mixer until well dispersed. Two grams of potassium lactate having an HLB value of 17 was dissolved in 50 ml of water and heated at 50° C. then added to the above mixture and mixed for 10 minutes. While this was being stirred, 2 chemical equivalents of zinc sulfate aqueous solution, based on the potassium lactate, was added dropwise. Two grams of potassium gluconate having an HLB value of 20 was dissolved in 50 ml of water heated at 50° C. then added to the above mixture and mixed for 10 minutes. While this was being stirred, 2 chemical equivalents aluminum sulfate aqueous solution, based on potassium gluconate, was added dropwise. The product was filtered using a Buchner funnel, followed by rinsing of purified water. The filter cake was then baked in an oven for three hours after the filter cake reached a temperature of 100° C. to further dehydrate the filter cake. The filter cake was crushed and further pulverized to a more workable powder after cooling. This resulted in black iron oxide pigment chemically immobilized coated with zinc lactate and aluminum gluconate.
