Abstract
Sorption of U(VI) on montmorillonite (M) of the Cherkassy deposit, with Al(III) and Fe(III) deposited on its surface in various amounts (1 and 5 wt %), was studied. The presence of such hydroxides increases the U sorption in the range pH 4.0–8.0. The U(VI) sorption increases in the order M < [M + 1% Al(III)] < [M + 5% Al(III)] < [M + 1% Fe(III)] < [M + 5% Fe(III)]. The U sorption isotherms on all the sorbents were obtained. The effect exerted on the sorption by artificial (ethylenediaminetetraacetic acid) and natural (fulvic acids) complexing agents was examined.
