G.N.DonoSoe在弱酸性介质中对铟与铜铁试剂配合物的吸附波进行了研究,陈德贞、叶华利也提出了铟与铜铁试剂的配合物的吸附波制定了较灵敏的测定铟的方法,马自成等提出了铟—碘配合物的吸附波。铟与巯基乙酸、联吡啶多元配合物的吸附波尚未见报道。我们在实验中发现,铟与巯基乙酸在HAc-NaAc介质中有一较灵敏的吸附波,加入适量联吡啶后,其灵敏度可再提高一个数量级,检出限为0.005μgml~(-1),较大量Fe~(3+)和一定量阴阳离子不干扰测定。由于Fe~(3+)不影
GNDonoSoe adsorption of indium and copper and iron reagent complexes in weak acid medium Chende Zhen, Ye Hua Li also proposed indium and copper and iron reagent complexes of the adsorption wave to develop a more sensitive method for the determination of indium , Ma Zicheng proposed indium - iodine complexes adsorption wave. Indium and thioglycolic acid, bipyridine multi-complex adsorption wave has not been reported. We found in the experiment, indium and thioglycolic acid in the HAc-NaAc medium has a more sensitive adsorption wave, adding an appropriate amount of bipyridine, the sensitivity can be an order of magnitude increase with a detection limit of 0.005μgml -1, compared with A large number of Fe ~ (3 +) and a certain amount of anion and cation do not interfere with the determination. Since Fe ~ (3+) is not affected
