Sulfate radical-based oxidation of the aminopyralid and picloram herbicides: The role of amino group on pyridine ring
The widespread utilization of pesticides has attracted increasing attention to their environmental impacts and effective removal strategies. In the present study, the degradation of herbicides picloram (PCLO) and amino-pyralid (AMP) with similar structures were investigated systematically by thermo activated persulfate. Overweight SO4 center dot- was determined to be the predominant oxidizing species by quenching experiment. Obtained by laser-flash photolysis (LFP), reaction rate constants of SO4 center dot- towards AMP and PCLO were determined at 1.56 x 10(9) M-1 s(-1) and 1.21 x 10(9) M-1 s(-1), respectively. Product analysis revealed that both substances underwent similar oxidation paths, namely, successive oxidation on pyridine ring and formation of coupling-products as well as further hydroxylation and decarboxylation. Amino group on the pyridine ring was identified as the main reactive site, which was further confirmed by DFT calculation. It was susceptible attacked by SO4 center dot- to form deamination, nitration, and self-coupling products. These couples could be further oxidatively dehydrated to form azo and a series of azo derivatives. EOCSAR program predicted significant hazards on aquatic species during the formation of these couplings and azo derivatives. Our work emphasized the potential ability and toxicity of contaminates to produce azo substances in the presence of amino groups on the pyridine ring.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 175358-01-7 is helpful to your research. Quality Control of 3-Amino-6-chloropicolinamide.
