実験手順

To 3.35 kg of water in a stirred crutcher were added 3.0 kg of ethylene diamine tetra (methylene phosphonic acid), followed by 1.7 kg of caustic soda flakes. When all the ethylene diamine tetra (methylene phosphonic acid) was dissolved, 3.95 kg of a zinc sulphate solution (made from 1.975 kg ZnSO4.7H2O in 1.975 kg water) were added slowly. The slurry obtained was drum-dried to obtain a particulate dry product.
