摘要
用结晶紫选择性电极（自制）以催化电位法对测定微量锰进行了研究。该方法测定标的线性范围为７～７４μｇ／Ｌ，对标准钢样中的锰含量测定结果满意，且操作方便。
A new catalytic kinetic potentiometric method for the determination of trace manganese is Propose. The propose method is based on the catalysis of manganese to the oxidation of crystal violet by KIO4. A crystal violet ion selective electrode is used to indicate the variation of Crystal violet concentration.The linear range of the method is 7～74μg/L ofMn (Ⅱ).This method has been used to determine the manganese content in standard steels,the results obtained are dose to the standard values.
