Determination of Trace Ga,In and Tl in Geological Samples by Stepwise Extraction-ICP-AES

    摘要
  • 摘要: 本文研究了分步萃取-ICP-AES法测定地质试样中痕量Ga、In和Tl的最佳条件。首先在pH9左右,用吡咯烷二硫代氨基甲酸铵(APLC)-甲基异丁酮(MIBK)萃取In和Tl,然后在6mol/LHCl介质中用MIBK萃取Ga,再将有机相分别直接引入ICP-AES进行测定。方法较简便实用,经地质标样验证,结果满意。

     

    Abstract: Optimal conditions were investigated for the determination of gallium, indium and thallium by stepwise extraction-ICP-AES. Indium and thallium were first extracted with APDG-MIBK from pH 9 solution, then gallium was extracted into MIBK from 6mol/L HC1 med
