Abstract

The samples are fused with Na2O2. After separation and enrichment of cation exchange resin,rare earth elements in sulfide ore are determined by HR-ICP-MS. Sensitivety drift are compensated by internal standard method. Light rare earth elements are determined by LR mode,heavy rare earth elements are determind by HR mode. Matrix interference and the interence of light rare earths on heavy reare earths are eliminated. The detection limits of the method are 0. 0005 ~ 0. 0121 μg /g,the precision are 1. 0% ~ 4. 6%.
