本文研究试验了水和废水中黑索金的分光光度测定方法。黑索金含量在0—10mg/l范围内符合比尔定律,回收率为95—105％,黑索金浓度为0.48mg/l时,十一次测定的相对标准偏差为2.91％,最小检出浓度是0.1mg/l。本文研究试验了黑索金定量分解的条件,试验了三十六种可能共存成份的影响及干扰的清除。方法的特点是:分析周期短,所用试剂及仪器简单、操作简便、能满足水和废水中黑索金测定的要求。
This paper studies the determination of spectrophotometry of desalination gold in water and wastewater. Beer’s law gold content in the range of 0-10mg / l Beer’s law is in line with the recovery of 95-105%, the concentration of the black gold 0.48mg / l, the relative standard deviation of the determination of eleven was 2.91%, the minimum detection The concentration is 0.1 mg / l. In this paper, we studied the conditions for the quantitative analysis of desmethyloxine, tested the influence of 36 possible coexisting components and the removal of interferences. The method has the following characteristics: short analysis period, simple reagents and instruments, simple operation, and can meet the requirements of determination of the black gold in water and wastewater.
