摘要

Abstract Oxidations of indigocarmine (IC) by chloramine-T (CAT) and aqueous chlorine (HOCl) in acidic buffer media, pH 2–6, have been kinetically studied at 30 C using spectrophotometry. The CAT reaction rate shows a first-order dependence on [IC] 0 and an inverse fractional order on [p-toluenesulfonamide]. The effect of [CAT] on the rate is strongly pH dependent with a variable order of 1–2 on [CAT] 0 in the pH range 6–2. The chlorine ...
