Abstract

The uranium removal from radioactive liquid waste using expanded perlite (EP) was studied. The influence of the contact time, solution pH, initial uranium concentration, sorption temperature, and mass/ volume ratio on the uranium sorption was examined. The theoretical capacity of EP adsorbent is about 95 mg g⁻¹. About 90% of the loaded U(VI) can be eluted with 1 M HNO₃.
