Abstract

The kinetics of Ru(III)-nicotinic acid complex formation by oxidation of bromamine-T (p-CH3C6H4SO2NBrNa) in acid solution at 35degreesC has been studied spectrophotometricaolly at lambda(max) 585 nm. The reactions rate shows first order dependence on bromamine-T, a fractional order dependence on nicotinic acid] and second order with respect to Ru(III)]. The reaction is inverse 1.5 order on H+] and also inverse second order on Cl-]. The variation of ionic strength, dielectric constant of the medium and the reaction product of BAT, p-toluene sulphonamide have no effect on the reaction. Activation parameters have been evaluated from the Arrhenius plot. A mechanism consistent with experimental results has been proposed.
