| 摘 要： | 比较了乙醚和甲基异丁基酮（MIBK）两种萃取剂对高纯镓中基体与杂质的分离效果。选择MIBK作为萃取剂，将高纯镓中的基体元素镓萃入有机相，绝大多数金属杂质则留在水相中，用电感耦合等离子体发射光谱法测定了水溶液中 的14种痕量元素。方法的加标回收率为805－110％，检出限在0.001-0.075ug/mL之间。

| Abstract: | Two kinds of extraction reagents, methyl isobutyl ketone (MIBK)and ether were compared according to their efficiency of separation of impurities from high purity gallium matrix and MIBK was selected as the extraction reagent. The matrix element was extracted into organic phase. Most of the impurities in aqueous solution were determined by inductively coupled plasma atomic emission spectrometry. The standard addition recovery was 80%～110% and the detection limits were in the range of 0.001～0.075 μg/mL. |
