LIGANDS FOR REMOVAL OF LIQUID PHASE CATIONS AND METHODS FOR SAME

The invention provides chemical compounds for binding to a liquid phase cation having the formula R -SO -S-R -SH, wherein R comprises a support molecule, such as a polymer, and R comprises an alkyl. The polymer may be a crosslinked, polystyrene divinylbenzene copolymer having a plurality of pendant benzyl groups to which the -SO -S-R -SH 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. 本发明提供具有式R1-SO2-S-R2-SH的用于结合到液相阳离子的化合物，其中R1包含载体分子(例如聚合物)，并且R2包含烷基。所述聚合物可以是具有所述-SO2-S-R2-SH配体附着至其的多个侧基苄基的交联的聚苯乙烯二乙烯基苯共聚物。所述烷基可以是乙基或丙基。所述化合物可以用于络合阳离子铅或汞，其中所述阳离子与所述硫代-磺酰基部分的巯基-硫和所述末端硫醇络合以形成结合所述阳离子的杂环状几何形状。还提供使用本发明的化合物从液体流去除阳离子的方法。
