摘要
提出了使用电感耦合等离子体-原子发射光谱法同时测定红土镍矿中Cd、Co、Cu、Mg、Mn、Ni、Pb、Zn、Ca的分析方法。采用盐酸、硝酸和氢氟酸处理样品,以盐酸作为测定介质,在选定的仪器工作条件下直接测定。各元素的测定检出限为0.0001~0.0033μg/mL,相对标准偏差（RSD,n=6）为0.15%~1.89%。对样品进行加标回收试验,回收率在91.4%~107.2%之间。经比对试验证明,本法测定值与火焰原子吸收光谱法测定值一致。
A new analytical method was proposed to simultaneously determine Cd,Co,Cu,Mg,Mn,Ni,Pb,Zn and Ca in laterite nickel ore by inductively coupled plasma atomic emission spectrometry（ICP-AES）.The samples were first treated by hydrochloric acid,nitric acid and hydrofluoric acid and then determined by ICP-AES under optimal instrument conditions with hydrochloric acid as the testing medium.The detection limits for each element were 0.0001%～0.0033 μg/mL and the relative standard deviations（RSD,n=6）were 0.15%～1.89%.The recoveries for testing the spiked samples were between 91.4%～107.2%.The comparison test showed that the values determined by ICP-AES were consistent with those by flame atomic absorption spectrometry.
