Adsorption of Uranium from Aqueous Solutions by Expanded Perlite

Аннотация

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.
