摘要
本文采用泡沫塑料富集分离金,拟定了金试剂—磷酸三丁酯液珠萃取比色测定化探样品中金的新方法.方法简单快速、灵敏度高,测定范围为0.5～5000ppb (称样15g).经样品验证结果满意.
Gold reagent-TBP liquid ball extration colorimetric determination of gold in geological samples has been developed, it is based on extraction of the color complex of gold-goldreagent by liquid ball of TBP at pH3.3 acetate buffer solution after preconcentration with polyurethane. It is simple rapid and highly sensitive. Range of determination with a 15g sample is 0.5-5000ppb. Satisfactory results were obtained.
