摘要
采用电感耦合等离子体发射光谱法测定了铜渣精矿中砷、锑、铋、铅、锌、镁的量。其测定范围：ω（As）：0.05%~0.45%,ω（Sb）：0.07%~0.30%,ω（Bi）：0.01%~0.20%,ω（Pb）：1.00%~4.50%,ω（Zn）：1.00%~4.50%,ω（Mg）：0.10%~1.00%。经加标回收实验,各元素的加标回收率为92%~104%（n=3）,相对标准偏差（RSD）小于5%（n=11）。方法准确快速可靠,适用于铜渣精矿中砷、锑、铋、铅、锌、镁量的同时测定.
A method for the determination of arsenic, antimony, bismuth, lead, zinc and magnesium oxide in copper slag concentrate by inductively coupled plasma emission spectrometry were established. The measurement ranges for As, Sb, Bi, Pb, Zn and Mg were obtained as follows： 0. 05%~0. 45% ,0.07%~0. 30% ,0.01% 0.20%, 1. 00%~4. 50%, 1. 00%~4. 50% and0.10%~l. 00%. The recovery was92%~104% （n=3）, and the relative standard deviation was less than 5 % （n = 11）. This proposed method is fast and accurate, making it suitable for simultaneous determination of As, Sb, Bi, Pb, Zn and Mg in copper slag concentrate.
