Purification of raw bentonite was done to remove quartz. This includes mixing the raw bentonite with water and then centrifuge it at 750 rpm; this process is repeated until white purified bentonite is obtained. XRD, XRF, FTIR, and SEM techniques will be used for the characterization of purified bentonite.

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<sup >∘</sup>C, 35.0<sup >∘</sup>C, and 45.0<sup >∘</sup>C. The Langmuir, Freundlich, and Dubinin-Radushkevich (D-R) sorption models equations were applied and the proper constants were derived. It was found that the sorption process is enthalpy driven for uranium(VI) and thorium(IV). Recovery of uranium(VI) and thorium(IV) ions after sorption was carried out by treatment of the loaded bentonite with different concentrations of HNO<sub >3</sub> 1.0 M, 0.5 M, 0.1 M, and 0.01 M. The best percent recovery for uranium(VI) and thorium(IV) was obtained when 1.0 M HNO<sub >3</sub> was used.
