Abstract

A new flow injection chemiluminescence method for determination of decomposition ratio of H2O2 in bleaching process was developed. It was based on the chemiluminescence of the K4Fe(CN)6-K3Fe(CN)6-H2O2-luminol system in basic medium.The detection limit for determination of H202 was 1.75×10-5 mol/L and the linear range was 2.1×10-5-1.7×10-2 mol/LThe relative standard deviation was 2.9%(5.8×10-3 mol/L, n=11).
