The invention provides chemical compounds for binding to a liquid phase cation having the formula R.sub.1SO.sub.2SR.sub.2SH, wherein R.sub.1 comprises a support molecule, such as a polymer, and R.sub.2 comprises an alkyl. The polymer may be a crosslinked, polystyrene divinylbenzene copolymer having a plurality of pendant benzyl groups to which the SO.sub.2SR.sub.2SH ligand is attached. The alkyl group may be ethyl or propyl. The chemical compound may be used to complex cation lead or mercury, in which the cation is complexed with mercapto-sulfur of the thio-sulfonyl moiety and the terminal mercaptan to form a heterocyclic ring-like geometry incorporating the cation. A method for removing cations from a liquid stream using the chemical compounds of the present invention is also provided.
