摘要
应用方波极谱,催化波测定矿石中微量铟已有报导,但仅限以测定0.Xppm以上样品中铟,而对岩石、土壤中测定0.0Xppm铟尚不多见。虽然用阳极溶出伏安法测定铟有一些文献报导,但却只能用于某些基体较为简单的样品如锌、铝及其合金水质中铟的测定。
A differential puls anodic stripping peak of indium appeared at.-0.52v(Vs Ag/AgCl)in a solution of 1.65N KBr-0.05NHCI-0.02%NH_(2)OH-HC1.Under this condition,In can be determination within the range 0.0004-0.02μgml^(-1).The detection limit was 0.04 ppb.The presence of 30-fold excess of Cd and 100-fold excess of Pd only causes negligible interference.The interference caused by other ions is prevented by the preliminary chromatographic separation.
