“…It is well known that aldehydes react with alcohol to give hemiacetals or acetals [41]. Results from this laboratory on the oxidation of Ni(II)-α-hydroxy carboxylates by PMS in the presence of formaldehyde show the formation of a hemiacetal intermediate [42,43]. Therefore, in the present study also the hydroxyl group of the tartarate and the oxo group of the product may react to form a hemiacetaltype intermediate.…”

“…[5][6][7] Thus it is this weak peroxide linkage (-O-O-) that undergoes cleavage during electron transfer reactions. [8][9][10][11][12][13][14][15] However, such peroxocompounds are exceptionally sensitive to the traces of metal-ions as has been observed in trace metal-ion catalysis in large number of reactions of peroxo acids.…”

ABSTRACT. The kinetics of oxidation of nicotinic acid by peroxomonosulfate (PMS) has been studied in acetate buffers. Stoichiometry of the reaction corresponds to the reaction of one mole of the oxidant with a mole of nicotinic acid. N→O product has been confirmed both by UV visible and IR spectroscopy. The reaction is second order viz. first order with respect to each reactant. Activation parameters have also been evaluated. A plausible reaction mechanism is mentioned and the derived kinetic rate law accounts for experimental observations.

“…The catalytic activity and oxidation state of transition metals influence the formation of reactive species such as sulfate radicals. A sulfate radicalbased mechanism was suggested when manganese, cobalt, copper, nickel, and silver transition metals were used [29][30][31][32][33][34], and the same was suggested as one of the most efficient pathways when iron transition metal was used [35].…”

The goal of the research was to devise a simple and environment-friendly approach to synthesize iron nanoparticles (FeNPs) and evaluate the catalytic activity of biosynthesized FeNPs for the degradation of the cationic dye Malachite Green (MG) in the presence of Peroxomonosulphate (PMS). Different instrumental approaches were used to characterize green produced FeNPs, and the results show that the NPs are spherical and 48 nm in size. Increasing the concentrations of nanoparticles (0.5 × 10-8 - 2.0 × 10-8 mol/dm3), Peroxomonosulphate (1.0 × 10-4 - 5.0 × 10-4 mol/dm3), dye (1.0 × 10-5 - 5.0 × 10-5 mol/dm3), pH (5), and high temperature (25-35 °C) enhanced the degradation kinetics of Pseudo-first-order kinetics were used to describe the degradation of MG in the FeNPs/PMS system, and activation parameters were derived. The maximum MG degrading efficiency for the FeNPs/PMS system was 88% in 60 minutes under optimum reaction conditions. The structure of intermediates formed by MG degradation by FeNPs/PMS was determined using UV-vis spectrum analysis. The application of synthesized FeNPs to improve Peroxomonosulphate oxidation potential for MG degradation is a unique, efficient, promising, and eco-friendly technology because it does not require any expensive reagents.
