摘要：

The selective liquid-liquid extraction of various alkali and transition metal cations from the aqueous phase to the organic phase was carried out by using p-tert-butylcalix[4]arene (L1), p-tert-butylcalix[6]arene (L2), tetraethyl p-tert-butylcalix[4]arene-tetra-acetate (L3), tetra-methyl-p-tert-butylcalix[4]arene-tetra-ketone (L4), calix[n]arenes (n=4 and 6) bearing oxime groups on the lower rim (L5, L6) and a polymeric calix[4]arene. It was found that compounds L5 and L6, showed selectivity towards Ag+, Hg+, Hg2+, Cu2+, and Cr3+ and the order of the extractability was Hg+>Hg2+>Ag+>Cu2+>Cr3+. The polymeric calix[4]arene (L8) was. selective for Ag+, Hg+ and Hg2+, unlike its monomeric analog.
