Flow-injection investigation of the chemiluminescent reaction of bis(2,4,6-(trichlorophenyl)oxalate) with free chlorine

摘要

This work investigated the chemiluminescent reaction of free chlorine with bis(2,4,6-(trichlorophenyl)oxalate) (TCPO) in the presence of 9,10-diphenylanthracdene in acetonitrile/water medium with analytical application for free chloring in tap water In the absence of free chlorine the background signal increased with the pH and the chemiluminescence emission showed strong dependence with the sample acidity A flow injection analysis system for free chlorine determination,was develeped The linear range for free chlorine was (0.2-0.3) X 10~-5 moll~-1 Chloramine 1.0 x10~-5 moll~-1 and chlortie 1.0 x 10~-6 moll~-1 also enhanced the chemiluminescence intensity.
