Formula: C6H2Cl3NO2On May 1, 2008 ,《Degradation of picloram by the electro-Fenton process》 appeared in Journal of Hazardous Materials. The author of the article were Oezcan, Ali; Sahin, Yuecel; Koparal, A. Savas; Oturan, Mehmet A.. The article conveys some information:
The degradation of the picloram, a widely used herbicide, was undertaken by the electrochem. advanced oxidation process, namely electro-Fenton in aqueous solution This process generates catalytically OH radicals that are strong oxidizing reagents for the oxidation of organic substances. Degradation kinetics of picloram was investigated. Kinetic results evidence a pseudo first-order degradation, with a rate constant of reaction between picloram and OH radicals of (2.73 ± 0.08) × 109 M-1 s-1. The effect of applied current and catalyst concentration on the degradation and mineralization of picloram was also investigated. The optimum applied current and catalyst concentration values for the degradation of picloram was determined as 300 mA and 0.2 mM Fe3+, resp. Mineralization of picloram was followed by the total organic carbon (TOC) anal. At the end of 8 h of electrolysis, 95% of the initial TOC was removed. Several degradation products were identified by using HPLC, LC-MS, GC-MS, and IC anal. The identified byproducts allowed to propose a mineralization pathway for the picloram degradation In the experiment, the researchers used many compounds, for example, 3,5,6-Trichloropicolinic acid(cas: 40360-44-9Formula: C6H2Cl3NO2)
3,5,6-Trichloropicolinic acid(cas: 40360-44-9) belongs to pyridine. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. As ligands, solvents, and catalysts they facilitate reactions; thus descriptions of these new ligands and their applications abound each year.Formula: C6H2Cl3NO2
