摘　　要：在ＨＣｌ－ＮａＡｃ介质（ｐＨ２．５）中，可获得灵敏的Ｉｎ（Ⅲ）－ＰＭＢＰ－Ｆｅｒｒｏｎ极谱络合吸附波，峰电位在－０．６５Ｖ处（ｖｓ·ＳＣＥ），检出限为０．０４ｎｇ／ｍＬＩｎ。峰电流与铟浓度在０．０８～２００ｎｇ／ｍＬ范围内呈线性关系。本法测定工业废水中的痕量铟，结果满意。本文还研究了极谱波的性质和机理。A sensitive adsorptive polarographic wave of indium(Ⅲ)-PMBP-Ferron complex can be obtained in a 0.04 mol/L HCl-0.036 mol/L NaAc buffer solution at pH 2.54.The peak appeared at -0.65 V(vs. SCE).The detection limit of indium is 0.04 ng/mL. The peak current is linearly related to the concentration of indium in the range of 0.08～200 ng/mL. The method has been satisfactorily applied to the determinaton of trace amount of indium in industrial waste water.The electrode reaction mechanism is also discussed.
