英文摘要The radio-frequency (RF) plasma-induced grafting technique was employed to fabricate a carboxymethyl cellulose (CMC) grafted magnetic bentonite composite (CMC-g-MB) in Ar conditions. The grafted CMC could improve the composite dispersion ability as well as the chemical stability in strong acidic conditions. The CMC-g-MB composite exhibited fast adsorption kinetics and good adsorption capacities in the enrichment of Cs(I), Sr(II) and Co(II) from aqueous solutions, showing broad applicability for radionuclide removal. The enrichment efficiencies of radionuclides on the CMC-g-MB composite decreased in the order of Cs(I) > Sr(II) > Co(II). On the basis of the thermodynamic parameters, radionuclide adsorption on the CMC-g-MB composite was thermodynamically favorable and endothermic. Considering the non-toxicity and biodegradation of CMC, the CMC-g-MB composite presented promising potential in radioactive pollution management.
