Use of polyelectrolytes in ultra- and nanofiltration treatment of uranium-contaminated waters

Radiochemistry Aims and scope

Abstract

The effect of water-soluble high-molecular-weight polyelectrolytes (polyacrylamide and its derivatives, Praestols) on ultra- and nanofiltration treatment of U(VI)-contaminated waters was studied. The influence exerted on the degree of U(VI) removal by pH and concentration of polyacrylamide and its derivatives was determined. The maximal coefficient of U(VI) retention by both ultra- and nanofiltration membranes, attained with these polyelectrolytes, was 0.999.
