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. (c) 2007 Elsevier Ltd. All rights reserved.
