摘要
本文提供了离子交换提金工艺过程树脂中金、银含量的快速测定方法。采用含硫酸的硫脲溶液,在沸水浴温度下能定量解吸树脂中金、银,并用原子吸收光度法分别测定。方法精密度优于4％,回收率为94—105％。
A rapid method has been established for determination of gold and silver in resin used in ion-exchange process for extraction of gold. The experiment results show that the gold and silver in resin can be quantitatively leached by thiourea solution in the presenc: of. sulfurjc acid and under the temperature of boiling water-bath, and can be determined by atomic absorption spectrophotometry. The precision of this method and recovery is 94-105%.
