摘要
建立了红土镍矿中镍含量的测定方法。红土镍矿样品经微波消解后,采用内标法校正基体干扰,用电感耦合等离子体-原子发射光谱法测定样品中镍元素含量。方法检出限为镍0.035mg.g-1,相对标准偏差(n=7)为1.2%—2.0%,加标回收率为100.5%—104.2%。
A method for the determination of nicekl in laterite ore is presented in this paper. Laterite ore sample was dissolved with HNO3, HC1 and HF by microwave digestion instrument. The sample solution was measured by inductively coupled plasma-atomic emission spectrometry （ICP- AES）. The dection limits for Ni was 0. 035mg · g-1. The relative standard deviations of test result were between 1.2%-2. 00% （n=7）,and the recoveries ranged from 100. 5% to 104.2%.
