Pigments based on thermally treated iron-containing slimes
Santrauka
The effect exerted by chemical and phase composition on the color characteristics of the products of a heat treatment of slime obtained at purification of model wastewaters containing prescribed amount of zinc(II), nickel(II), copper(II), and chromium(III) compounds using ferroferrihydrosol was studied. The dependence of pigment properties of the products of the heat treatment of slimes on the concentration of metal compounds in them was determined.
