Electrochemical oxidation of 2,4-Dichlorophenoxyacetic acid: Analysis of by-products and improvement of the biodegradability

Reaction Kinetic Model for 2,4-Dichlorophenoxyacetic Acid Decomposition in Aqueous Media Including Direct Photolysis, Direct Ozonation, Ultraviolet C, and pH Enhancement

“…Once more, the kinetic scheme corresponding to the 24 stages of reaction can be assembled (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) that describe the decomposition of ozone to include the generation of hydroxyl radicals, and 21-26 corresponding to the interaction of 2,4-D, 2,4-DCP and 2-CHQ with molecular ozone and OH radicals, respectively) and solve the corresponding mass balances for the species involved.…”

A new bipyridyl cobalt complex for reductive dechlorination of pesticides

“…The devices used are detailed in a previous work [4]. The analytes were separated by a Waters Acquity UPLC system (Waters corporation, Milford, MA, USA), consisting of an Acquity UPLC binary solvent manager, an Acquity UPLC sample manager and an Acquity UPLC column heater equipped with a Waters Acquity UPLC BEH C18 column (2.1 mm × 100 mm, 1.7 μm particle size) thermostated at 45 Ion chromatography.…”

“…Several physicochemical methods have been proposed for their degradation [1][2][3][4][5][6]. Among them, the catalytic reduction of chlorinated compounds has been the subject of numerous investigations because of its high importance both for synthetic chemistry and environment [6][7][8][9][10][11].…”

Electrocatalytic reduction of metronidazole using titanocene/Nafion®-modified graphite felt electrode

“…The devices used are detailed in previous works [13]. The analytes were separated by means of a Waters Acquity UPLC system (Waters corporation, Milford, MA, USA) consisting of an Acquity UPLC binary solvent manager, an Acquity UPLC sample manager and an Acquity UPLC column heater (45 °C) equipped with a Waters Acquity UPLC BEH C18 column (2.1 mm × 100 mm, 1.7 μm particle size) (Milford, MA, USA).…”

“…Several studies on the use of these methods to achieve the pretreatment of recalcitrant pollutants have been carried out. They have shown their efficiency for the removal of several recalcitrant molecules such as phosmet an organophosphorous insecticide [14], a chlorinated phenoxy herbicide 2,4-dichlorophenoxyacetic acid [6,9,13] and extensively used antibiotics such as sulfamethazine [19] and tetracycline [17].…”
