摘要
研究了用还原剂亚硫酸钠还原分金液中的金离子,确定了电位与金离子质量浓度及金还原率之间的关系。结果表明:电位降到585mV以下时,金还原率可达99%;电位约为505mV时,还原反应结束。
The gold ion in liquid is reduced using sodium sulphite as reductant.The relation between 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 when the redox potential is about505 mV,the reduction reaction of gold ion will end.
