Abstract
The kinetics of oxidation of indigo carmine (IC) by N-sodio-N-bromotoluenesulfonamide or bromamine-T (BAT) in pH 5 buffer medium has been investigated at 30 degrees C using spectrophotometry at 610 nm. The reaction rate shows dependencies of first-order on IC](0), second-order on BAT](0) fractional order on H+], and inverse first-order on p-toluenesulfonamide]. The addition of chloride and bromide ions, and the variation of ionic strength of the medium have no influence on the reaction rate. There is a negative effect of the dielectric constant of the solvent. Activation parameters have been calculated. A single-pathway mechanism for the reaction, consistent with the kinetic data, has been proposed. (C) 1997 John Wiley & Sons, Inc.
