摘要
电感耦合等离子体光谱法测定西藏铜矿浸出液中8种矿物组分,讨论了元素分析谱线选择、背景校正等因素。结果表明,在高海拔地区仪器参数优化条件下,元素间也没有干扰且该方法快速,准确可靠,各元素检出限5.6~42μg·m L^-1之间,加标回收率为92.5%~106%,相对标准偏差RSD均小于1.0%,适用于高海拔条件下对铜矿浸出液的日常检测。
8 kinds of mineral components in Tibet＇s copper ore leaching solution were determined by the analysis method ICP-OES, the choice of analytical spectral lines for elements and the background correction factors such as deduction were studied. The results showed that in the condition of parameter optimization in high altitude area instrument, no interference between elements and the method was rapid, accurate and reliable, the detection limits of this method were 5.6 -42 μg·m L^-1, the recovery rate was 92.5% - 106%, the relative standard deviation was less than 1%, daily inspection on copper ore leaching solution was suitable for high altitude conditions.
