文摘

An easy-to-get and low-cost Cs+-recognizable polymeric hydrogel has been developed. The hydrogel displays rapid and selective adsorption towards Cs+. Synergistic effect of AAc units and Cs+(B18C6)2 host-guest complexes is good for adsorption. The hydrogel shows great potential for decontamination of Cs+ from radioactive contaminants.
