Abstract
Thiacrown polymers immobilized to a polystyrene-divinylbenzene matrix react with Hg under a variety of conditions to efficiently and selectively remove Hg 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.
