对Ｉｎ（Ⅲ）－桑色素（ｍｏｒｉｎ）配合物在悬汞电极上的吸附伏安特性作了研究，确定了电极过程。在ＣｌＣＨ２ＣＯＯＨ底液中，有桑色素存在下，用１．５次微分吸附伏安法测定铟，线性范围和检测下限分别为３．５×１０－１０～１．５×１０－７ｍｏｌ／Ｌ和５×１０－１１ｍｏｌ／Ｌ。用此法测定了氢氧化铝、银粉和铅粉样品中的痕量铟，结果满意。
The adsorption voltammetry of In (Ⅲ) - morin complex on the hanging mercury electrode was studied, and the electrode process was established. In the presence of morin in ClCH2COOH at the bottom of ClCH2COOH, the linear range and the detection limit of indium were 1.5 × 10 -10 ~ 1.5 × 10 -7 mol / L and 1.5 × 10 -7 mol / L with differential scanning voltammetry 5 × 10-11mol / L. The trace amounts of indium in aluminum hydroxide, silver powder and lead powder were determined by this method. The results were satisfactory.
