The kinetic parameters of the reaction were studied by the spectrophotometric method using the trace vanadium catalyst of potassium bromate in acid medium to oxidize the colorimetric reaction of azomethine H. The results show that the reaction is a first-order reaction for azomethine H and vanadium respectively, Potassium bromate is a reaction of level 15. The reaction mechanism was preliminarily discussed as the formation of free radicals by the homogeneous cleavage reaction followed by the reaction between free radicals
