Polarographic Behaviour of Nitroacetanilides in Presence of some Ionic and Non-ionic Surfactants vis-a-vis their Effect on Kinetics of the Electrode Reaction

Polarographic behaviour of o-, m- and p-nitroacetanilides (in 25percent ethanolic solution) has been studied at 25+/-0.1 deg in Britton-Robinson (BR) buffer of pH 6.1 in the presence of increasing amounts of nine different ionic and non-ionic surfactants.Each depolariser gives a single 4-electron reduction wave which has been found to be diffusion-controlled and irreversible.A decrease in the value of kinetic parameters (αna and k0f,h) with the increasing concentrations of ionic and non-ionic surfactants shows that the irreversible electrode reactions of o-, m- and p-nitroacetanilides tend to become increasingly more irreversible.This is supported by a decrease in id abd a negative shift in E1/2 with increasing concentrations of the surfactants.A tentative mechanism of the polarographic reduction of nitroacetanilides has also been proposed at pH 6.1.The ease of reduction of the three isomers at d.m.e. is in the order, ortho > meta > para.

Investigations of the Kinetics and Mechanism of Polarographic Reduction of o-, m- and p-Nitroacetanilides in Aqueous Ethanolic Medium

Polarographic behaviour of o-, m- and p-nitroacetanilides in aqueous ethanolic solutions has been studied as a function of pH using NaNO3 (0.1 M) and Triton X-100 (0.001 percent) as the supporting electrolyte and maxima suppressor, respectively with a view to investigate the kinetics and mechanism of the reduction of o-, m- and p-nitroacetanilides at d.m.e.The reduction of the depolarizers has been found diffusion-controlled and irreversible.The potential-dependent rate constant, kf,h, has been calculated by Koutecky's method at different pH and the values of kinetic parameters (αna and k0f,h) have been calculated from log kf,h vs Ed,e plots which are linear thereby indicating that only a single rate-determining step is involved in the electrode process of each depolarizer.Based on the values of αna and the variation of E1/2 with pH, the stoichiometry of the rate-determining step involved in the reduction of each depolarizer at d.m.e. has been established.A tentative mechanism for the polarographic reduction of each depolarizer has been postulated.
