Abstract
Bentonite dolomite mixture composites were prepared by precipitation technique. The composition of these composite materials was established by different analytical tools; IR, XRD, TGA&DTA, XRF, and BET. X-ray peak broadening analysis was used to evaluate the crystallite size and lattice strain by Scherrer’s formula and Williamson–Hall (W‚ H) analysis. The variation of adsorption of 152+154Eu3+, La3+, Ce3+, and Sm3+ onto studied materials was carried out and the equilibrium time was carried out after 24 h. The capacity of radionuclide (152+154Eu3+) and some lanthanides (La3+, Ce3+, and Sm3+) were investigated, and all studied materials were selective for 152+154Eu3+.
