    This paper reports on the studied results of the sorption ability of the grafted chitosan with citric acid via crosslinking with glutraldehyde (C-Gch). The results obtained shown that after grafting citric acid on crosslinked chitosan, the adsorption capacity for U(VI) was significantly enhanced. Effects of the adsorption process including contact time, pH, initial concentration and some of metal ions were investigated. It was found that the maximum capacity obtained was172mg/g after 300 min of contact time and at pH 4. In the presence of cations such as Cu (II), Zn (II), Pb (II) and Cd (II), the adsorption capacity for U(VI) was reduced. The effect of these metals on the adsorption of U(VI) by C-Gch was arranged in the order: Cu (II) > Zn (II) > Cd (II) > Pb (II). The experimental data good fitted the pseudo second order model with correction coefficients R2 ≥ 0.995 fo.. Read More»
