摘要： It has been discovered that relatively large cyclic and open chain carbonates are extremely efficient in the selective extraction of metal ions, such as gold, silver, platinum and mercury from aqueous solution without the need for a potentially hazardous, organic solvent or use of a corrosive salt, such as NaCl. For example, 1,2-decane carbonate extracted >99.9% mercury, 99.76% gold, 97.5% silver and 79.0% platinum. The homologous 1,2-dodecane carbonate was found to extract 99.9% gold and silver from aqueous solution and 95.8% platinum. Didecyl carbonate extracted 77% gold from aqueous solution. The method of this invention is simpler than prior techniques and eliminates the need for potentially hazardous solvents (toxic, flammable and environmentally unfavorable) and corrosive additives, such as salt, NaCl, used as a salting agent in prior methods.
