Description
The performance of a cross-linked magnetic chitosan has been investigated for the adsorption of U(VI) from aqueous solutions. The influences of the pH of solution, the initial concentration of U(VI) ions and the contact time on the adsorption amounts have been discussed, and the appropriate process conditions for the adsorption of U(VI) have been obtained. The adsorption experimental equilibrium data was found to fit the Langmuir model well, and the uptake of U(VI) was 161.3 mg g-1. Two simplified models including pseudo-first order and pseudo-second order equations are selected to follow the adsorption process. (author)
