中文摘要: 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0.0001~0.0033 μg/mL,相对标准偏差(RSD,n=6)为0.15%~6.95%。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。
Abstract: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 0~0.0033 μg/mL and the relative standard deviations (RSD,n=6)were 0.15%~6.95%. 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.
