摘要：
A new kinetic method for determination of traces of Mn(II) has been developed. The method is based on the catalytic effect of Mn(II) on the oxidation of trimethylenediamine-N,N,N',N'-tetra acetic acid (TDTA) by KMnO4 in acid media. Under optimal conditions the limit of determination of Mn(II) was 0.5 ng mL(-1). The probable relative error was 4.0-2.8% in the concentration range of Mn(II) 1.0-5.0 ng mL(-1). Limit of detection was 0.12 ng mL(-1). The effects of certain foreign ions upon the reaction rate were determined in order to assess selectivity of the method, which was found relatively good. Kinetic equations for the investigated process were proposed. The method has been applied to the determination of Mn(II) in natural water.
