微波消解-原子荧光法测定铜精矿中的铅方法研究

Determination of lead in copper concentrate by microwave digestion and atomic fluorescence spectrometry

文章研究了微波消解-原子荧光光谱法连续测定铜精矿中铅的最佳实验条件,提出了原子荧光光谱仪连续测定铜精矿中铅的方法。铅的检出限为0.2μg/L,相关系数R均大于0.998。铅测定的回收率为88.1%~94.2%,RSD值在1%~4%。

Optimum experimental conditions for continuous determination of plumbum in copper concentrates bymicrowave digestion and AFS are studied. A method for continuous determination of lead in copper concentrates byatomic fluorescence spectrometer is presented. The detection limits of 0.2 g/L, correlation coefficient R are greater than0.998. The recovery rate of lead is 88.1%—94.2%, and the RSD value is between 1%—4%.
