The primary objective of this study is the sorption of uranium and thorium by purified Jordanian bentonite from Al-Azraq at different pH = 1.0, 2.0, and 3.0, at different temperature 25.0°C, 35.0°C, and 45.0°C, and different contact time. The purification of raw bentonite
Recovery of uranium(VI) and thorium(IV) ions after sorption was carried out by treatment of the loaded bentonite with different concentrations of HNO3 1.0 M, 0.5 M, 0.1 M, and 0.01 M.

Bentonite has shown high metal ion uptake capacity toward uranium(VI) than thorium(IV). Sorption data were evaluated according to the pseudo- second-order reaction kinetic. Sorption isotherms were studied at temperatures 25.0∘C, 35.0∘C, and 45.0∘C.
