摘要
Abstract
T he gold ion in liquid is reduced using sodium sulphite as reductant .T he relation betw een liquid redox potential and gold ion concentration and gold ion reduction rate based on gold ion concentration were determined .Theoretically ,it can be determined when the redox potential drops below to 585 mV ,the reduction rate of gold ion can reach 99% ,and w hen the redox potential is about 505 mV ,the reduction reaction of gold ion will end .关键词
