摘要：

A kinetie method is described for the determination of trace amounts of mangancsc (Ⅱ)based on its catalylic effect on the aerial oxidation of 1.5-bis (2-hydroxy-5-chlorophenyl)-3-cyanofrmazan. The reaction is followed spectrophotometrically by measurin the rate of change in absorbance at 580nm. The calibration curve (rate constant vs. manganese concentration) is linearin the range of 10～200ng in 25ml solutions. Kinetic parameters of the reaction are reported. Thereare few Interferences.
