| 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 medium and the elements in two organic phases were determined respectively by ICP-AES. This method is applicable to the determination of trace gallium, indium and thallium in geological samples with satisfactory results. |
