Abstract

The uranium sorption on PEI-CLT sorbents was studied experimentally from different carbonatecontaining
waters. The ranges of pH values and concentrations of NaCl were established for realizing
maximum uranium sorption capacity. The mathematical model with film- diffusion kinetic was chosen for
calculation the dynamic uranium sorption from surface water and from 0,5 N NaCl solution. The dynamic
desorption of uranium from sorbent with 0,5 N HCl solution was carried out. The degree of concentration
uranium in maximum of curve was 5.103.
