溴化法提金液中溴的测定

The Determination of the Bromine Density in the Extracting Gold Agent of Bromination

用铜试剂（二乙氨基二硫代甲酸钠）消除溴化法提金液中的干扰元素，用碘量法可快速准确地监控澳化法提金过程中溴的变化。精密度优于±２％，标准回收９６％～１００．５％。

he disturbing elements are dispelled in the extracting gold agent of bromination with sodium diethyldithiocarbamate. In the process of the extracting gold of bromination, the variation of the bromine density is monitored quickly and accurately with iodimetry. The precision of this way is below ±2%,and the standard recovery rate of bromine is from 96 % to 100. 5%.
