二安替比林苯甲烷在催化动力学分析中的应用

Application of diantipyrylphenylmethane in catalytic kinetic spectrophotometry

研究了在磷酸介质中，锰（Ⅱ）催化高碘酸钾氧化二安替比林苯甲烷（ＤＡＰＭ）的显色反应，建立了一种测定微量锰的催化动力学新方法。本方法的测定范围为０．５～２０μｇ／２５ｍＬ。用于铝合金等样品中锰含量的测定，结果满意。

This paper studied the colour reaction based on the manganese(Ⅱ) catalyzed oxidation of diantipyryl phenylmethane by potassium periodate in H 3PO 4 medium.A new catalytic spectrophotometric method for the determination of microamounts of manganese has been developed.The range of determination is 0.5～20μg/25mL.The method has been used in the determination of manganese in aluminium alloys with satisfactory results.
