METHOD FOR ADSORPTION OF CHROMIUM (VI) ON ACTIVATED CARBON

摘要

FIELD: extraction of substances by ion-exchange materials; applicable in nonferrous and ferrous metallurgy and also in treatment of industrial and household sewage. SUBSTANCE: method for adsorption of chromium (VI) on activated carbon includes treatment of adsorbent and solution, contact of adsorbent and solution, adsorption on activated carbon in weakly acid or acid medium with regulation of pH by continuous neutralization of the solution to optimal values. The method may be applicable in production of chromium and its compounds, in other industries using chromium in analytical chemistry, for treatment of sewages of electrochemical processes, leather production and others. EFFECT: higher efficiency. 1 cl, 3 dwg, 1 tbl
