摘　　要：本文研究了在碱性介质中，以邻菲啉为活化剂，锰（Ⅱ）催化高碘酸钾氧化苯酚红褪色指示反应及其动力学条件，建立了测定痕量锰的新方法．锰的浓度在0～0．07μg／ml范围内为线性关系，检测限为3．0μg／ml．用于盐酸试剂中痕量锰的测定，结果良好．In basic medium, taking o-phenanthroline as actirator, We used Mn (Ⅱ) catclysis KMnO4 and the kinetic condition of reaction was indicated by (C6H4OH)2 COC6H7SO2. Through this reaction, We established a new method of measuring trace metal Mn. In the range of 0~0.07μg/ml,the concentration of Mn appeared linear relation ship. The limit of detection was 3. 0μg/ml. It has been well applied in measuring trace metal Mn in HCl reagent.
