Abstract: A chemical relaxation kinetics analysis(CRKA) method has been proposed for the first time. The basic theory has been proved systematically and was applied to determine trace copper. Stopped-flow equipment was used for analyzing the system of Fe(Ⅲ)-S2O32- catalyzed by Cu(Ⅱ). We studied the influence of pH value, medium and reagent on relaxation parameter (1/τ) and obtained the linear relation of 1/τ and concentration. The analytical results of synthetic samples show that the CRKA method has an obvious advantage.

Key words: Chemical relaxation, Catalysis kinetics analysis, Copper
