This communication describes preparation, characterization, and the evaluation of sorption properties of a calix[4]arene-based chitosan polymer (C[4]BCP). C[4]BCP was used to sorption studies of some heavy metal cations (Co(2+), Ni(2+), Cu(2+), Cd(2+)(,) Hg(2+) and Pb(2+)) and dichromate anions (Cr(2)O(7)(2-)/HCr(2)O(7)(-)) as sorbent material. Also the supporting material (chitosan) was used for comparison in these experiments. The results for heavy metal cations showed that C[4]BCP was excellent sorbent and the effect of chitosan was low. In the sorption studies of dichromate anions, C[4]BCP was highly effective sorbent at pH 1.5.
本通讯描述了基于杯[4]芳烃的壳聚糖聚合物（C[4]BCP）的制备、表征及其吸附性能评估。C[4]BCP用作吸附剂材料，用于某些重金属阳离子（Co(2+)、Ni(2+)、Cu(2+)、Cd(2+)、Hg(2+)和Pb(2+)）以及重铬酸根阴离子（Cr₂O₇²⁻/HCr₂O₇⁻）的吸附研究。在这些实验中，还使用了载体材料（壳聚糖）进行比较。重金属阳离子的结果表明，C[4]BCP是优异的吸附剂，壳聚糖的效果较低。在重铬酸根阴离子的吸附研究中，C[4]BCP在pH 1.5时是高效吸附剂。
