Electrochemical degradation of herbicide 2,4-dichlorophenoxyacetic acid (2,4-d) in acidic water solutions on the platinized platinum anode

Anode oxidation of herbicide 2,4-D on the platinized platinum electrode in acidic water solutions in the galvanostatic mode was investigated. Degree of degradation for 2,4-D was detected by a decrease of the total organic carbon with increasing electrolysis time and on reduction of peak 2,4-D in UV a spectrum. Speed of decomposition 2,4-D in a sour water solution correspond to the equation of the first order with rate constant equal to 6 ⋅ 10-5 s-1.
On the basis of analysis UV, IR and chromatography-mass-spectra made assumptions about possible intermediate products of decomposition.
