Thiacrown polymers immobilized to a polystyrene-divinylbenzene matrix react with Hg2+ under a variety of conditions to efficiently and selectively remove Hg2+ ions from acidic aqueous solutions, even in the presence of a variety of other metal ions. The mercury can be recovered and the polymer regenerated. This mercury removal method has utility in the treatment of industrial wastewater, where a selective and cost-effective removal process is required.

A novel C-substituted crown thioether has been synthesized and used to prepare a cross-linked polystyrene polymer containing pendant crown thioethers and that product has been shown to be effective in extracting HgII from acidic aqueous solutions.
