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