Очистка жидких радиоактивных отходов от урана методом комплексообразования и ультрафильтрации

Abstract

The purification of model aqueous solutions and liquid radioactive waste (LRW) from uranium has been studied. We have been used first synthesized amino compound oligoether (AOE) containing phosphorus acid groups (OEPh) and the known polymers — branched polymer polyethyleneimine and polyacrylamide. The ultrafiltration membrane method was used as well. The fractional retention of uranium decreases in series: AOE ≥ OEPh ≥ polyethylenimine ≥ polyacrylamide. The elaborated purification method of LRW from uranium by using the complexation on the developed polymers and the further ultrafiltration can be used in the areas suffered from the accident at the Chernobyl NPP and areas of the extraction and reprocessing of uranium ores.
