摘　　要：本文采用甲酸还原硅钼酸——动力学分光光度法测定硫代硫酸盐浸取液中金.对硫代硫酸盐浸取用液以及浸取后液中杂质对金测定的影响进行了考察.方法标准偏差0.76%,变异系数24.5‰.为硫代硫酸盐法提金动力学实验提供了有效的分析方法.Determination of gold in the thiosulfate leaching solution have been carried out by kinetic spectrophotometry. The effects of impurity in the thiosulfate solution before and after leaching on determination of gold have been detected. The standard deviation of the method is 0.76%,and the coefficienf of variation is 24.5‰. The kinetic test for extracting gold by thiosulfate method provided an available analytical method.
