Summary: The paper has investigated the impact of water-soluble macromolecular polyelectrolytes on the ultra- and nanofiltration process of purification of waters polluted by U(VI) and Cr(VI). Derivatives of polyacrylamide—cationic and anionic Praestols were used as such compounds. The relationship between the degree of extraction of U(VI) and Cr(VI) and the pH and concentration of Praestols was found. It has been shown that when using the latter the maximum retention coefficient of U(VI) both by ultra- and nanofiltration membranes constituted 0.999; the maximum retention coefficient of Cr(VI) by the ultrafiltration membrane—0.65
