The as-prepared membranes can effectively reduce Lanthanide elements concentrations, in the radioactive waste water; furthermore, it can also simplify wastewater treatment process. The reaction mechanism of cellulose composited membranes and effect of adsorption on different preparatory parameter will be investigated by using XRD, Rama, SEM, AA, ICP, EDS techniques. Cellulose composited membrane sorbent materials have strong sorption capabilities for lanthanide ions, such as Cs+, Ce2+, Co2+, Eu2+, Gd3+, La3+, Nd3+, Sm3+, Sr2+, Y3+ etc. After ion adsorption characterization for 10 different metal ions, INER composited membrane has best removal rate of 56%, and MST composited membrane with the removal rate of 96% for Cs+ ion, particularly.
