The highly effective removal of Cs+ by low turbidity chitosan-grafted magnetic bentonite
Chitosan-grafted magnetic bentonite (CS-g-MB) was successfully synthesized via a plasma-induced method. The CS-g-MB composite shows good magnetic properties, low turbidity, and high stability in aqueous solution and exhibits significant adsorption capacity for Cs+ ions. The adsorption of Cs+ by CS-g-MB is dependent on both pH and ionic strength. In the presence of Mg2+, K+, Li+, and Na+ ions, the Cs+ exchange is constrained in the order of Li+ approximate to Mg2+
