摘要

Separation of cobalt, strontium, cerium and lanthanum was studied using ecofriendly grafted polymer (chitosan-AMPSNa-DMAEM). Characterization of prepared polymer and batch experiments are carried out. Adsorption isotherms and kinetics were applied to analyze the data. Freundlich model were found to be more fitted than langmuir model for Co+2, Ce+3, and La+3. The pseudo-second order, and Elovich kinetic models were applicable. The high separation factor of Ce+3 from Co+2, Sr+2 and La+3 indicates the selectivity of the prepared material for cerium ions. The removal percent of Co2+, Sr2+, Ce3+, and La3+ is 79.5, 55.2, 91.1, 68.5%, respectively.
