“…These pollutants are known to be toxic and difficult to remove by conventional biotechnology, which was believed to be an efficient and economical method to treat organic wastewater [2]. Oxadiazon (molecular formula C 15 H 18 C l2 N 2 O 3 ), which belongs to the chlorinated organic compounds, is a pre-emergence and post-emergence herbicide used widelyin many countries [3][4][5][6] to control weeds in agricultural fields. The chemical structure of oxadiazon is illustrated in figure 1.…”

To explore the feasibility of a degradation approach by non-thermal plasma and the corresponding degradation pathways, studies on the oxadiazon removal in synthetic wastewater by a dielectric barrier discharge plasma reactor were investigated. The loss of the nitro group, dechlorination and ring cleavage is mainly involved in the non-thermal plasma degradation pathways of oxadiazon in a solution based on the OES and LC-MS analysis. Detection of EC25 and the production of the chlorine ion and nitrate ion further demonstrate the feasibility and validity of the approach. The conditions with a proper applied voltage, solution flow rate, oxygen flow rate, and solution pH contribute to the plasma degradation processes with a degradation ratio of over 94%.

“…The thermal behavior of organic pesticides has already been investigated, especially for the disposal of waste pesticides by incineration (McPherson and Johnson, 1956; Kennedy et al, 1972;Holloman et al, 1976;Ahling and Wiberger, 1979). In previous papers, we gave the results of our work on the thermal degradation of diuron and iprodione (Gomez et al, 1982a), oxadiazon (Gomez et al, 1982b), and phosalone (Bruneau et al, 1986). The present investigation deals with the analysis of the products resulting from pyrolysis in an atmosphere of helium of three widely used chlorophenoxy acid herbicides [(2,4-dichlorophenoxy)acetic acid (2,4-D), (2,4-dichlorophenoxy)propionic acid (2,4-DP), (2-methyl-4-chlorophenoxy)acetic acid (MCPA)] in the range 200-1000 °C.…”
