Extraction of gallium(III), indium(III) and thallium(III) with n-octylaniline in chloroform at various concentrations of hydrogen halide acids (HCl, HBr, HI) has been studied and a scheme for their separation proposed. The procedure can be successfully applied to the separation and determination of gallium in presence of mercury, bismuth, manganese, zinc and lead; indium in presence of bismuth, antimony, lead, mercury, cadmium and zinc; and thallium in presence of mercury, cadmium, manganese, aluminium, tin and antimony. The advantage of the method is that the reagent can be recovered for reuse. The method is simple, rapid, and effects clear-cut separation.
研究了在不同浓度的卤化氢酸（盐酸、氢溴酸、氢碘酸）存在下，用正辛基苯胺在氯仿中萃取镓（III）、铟（III）和铊（III）的情况，并提出了它们的分离方案。该方法可成功应用于在汞、铋、锰、锌和铅存在下镓的分离和测定；在铋、锑、铅、汞、镉和锌存在下铟的分离和测定；以及在汞、镉、锰、铝、锡和锑存在下铊的分离和测定。该方法的优点是试剂可回收再利用。该方法简单、快速，能实现清晰的分离。
