ABSTRACT
A rapid and sensitive flow-injection chemiluminescence method is described for the determination of dichloro- and trichloroisocyanuric acids based on the chemiluminescence produced during their reaction with luminol in alkaline medium. The effects of analytical and flow-injection variables on these chemiluminescence systems and determination of both oxidants are discussed. The optimized method yielded 3σ detection limits of 8×10–8 and 5×10–8 mol L–1 for the sodium dichloroisocyanurate and trichloroisocyanuric acid, respectively. The optimum conditions were found to be as follows: NaOH, 1×10–1 mol L–1; luminol, 5×10–3 mol L–1; KI, 2×10–3 mol L–1 and flow rate, 3.5 mL min–1.
