The groups of LIU Jinhuai and KONG Lingtao’s from the Institute of Intelligent Machines, Hefei Institutes of Physical Science, prepared β-cyclodextrin polymers crosslinked with rigid aromatic groups and tested for lead (Pb), copper (Cu) and cadmium (Cd) removal. The negatively charged β-CD polymers showed adsorption capacities at 25 oC for Pb, Cu and Cd of 196, 164 and 136 mg/g when the initial concentration was 200 mg/L. The adsorption process was completed in 5 min.
