Abstract

Method of radioactive tracers was used to study the coprecipitation of 3d-element impurities from KH2PO4 solutions on hydrated potassium-aluminum phosphate. The influence exerted by the mass of the collector, its contact duration with solution, pH value and concentration of KH2PO4 on the process efficiency was examined. The purification coefficients were calculated. The high efficiency of the process of KH2PO4 purification was demonstrated.
