ABSTRACT:
A process of separating one or more seleced species of ions from a solution containing the ions comprises contacting the solution with a novel composition of matter comprising a hydrocarbon chain covalently bonded to a macrocyclic compound, wherein the macrocyclic compound has at least four --A--C--C-- linkages in which A for each such linkage, is independently selected from the group consisting of O, O--CH.sub.2, S, SH.sub.2, NR, and NRCH.sub.2, with R being independently selected from the group consisting of hydrogen, alkyl and benzyl, and wherein the hydrocarbon chain has an end group ##STR1## with X being independently selected from the group consisting of lower alkyl, benzyl, phenyl, halogen, O--CH.sub.3, O--C.sub.2 H.sub.5 and O-matrix, and with matrix being independently selected from the group consisting of silica, silica gel, glass, glass fibers, titania, zirconia, alumina and nickle oxide. A complex is formed between the selected ions and the composition of matter to remove the selected species of ions from the solution. The solution is separated from the complex, and the complex is thereafter contacted with an eluant which frees the selected ions from the complex into solution in the eluant.
