| 摘 要： | 红土镍矿样品用无水Na2CO3-Na2B4O7混合熔剂熔融,HCl浸出酸化,电感耦合等离子体发射光谱法直接测定样品中镍、钴、铜的含量。Cu 324.754 nm使用Y 371.030 nm作为内标线,Ni 231.604 nm、Co 228.616 nm使用Y 224.306 nm作为内标线校正基体干扰,方法检出限镍为0.5μg/g、钴为1.0μg/g、铜为1.0μg/g,相对标准偏差(RSD,n=7)为1.2%～2.0%,加标回收率为95.0%～103.6%,能满足红土镍矿的分析要求。

| Abstract: | A method for the determination of Ni,Co and Cu contents in laterite is presented in this paper.Laterite samples were fused with a mixed flux of Na2CO3-Na2B4O7,then the analytes were extracted by HCl acid.The sample solution was measured by inductively coupled plasma-atomic emission spectrometry(ICP-AES).The internal standard method was used to avoid matrix interference based on choosing Y 371.030 nm as the internal calibration line for Cu(324.754 nm) and Y 224.306 nm for Ni(231.604 nm) and Co(228.616 nm).Th... |
