Complexation studies were made by using liquid-liquid and solid-liquid extraction procedures. It was found that the soluble polymeric thiacalix[4]arene derived from terephthaloyl dichloride is better at removing alkali (Li+, Na+, K+, and Cs+) and heavy metal (Cu2+, Cd2+, Hg2+, Pb2+, Co2+ and Ni2+) cations than the precursor thiacalix[4]arenes. Both the soluble polymer and the cross-linked polymer derived from Merrifield's resin are more efficient at removing transition metals from solution than the precursor thiacalix[4]arene.
