Aised concern about the toxicity Rapamycin Mtor inhibitor of t of by-products of degradation. Compound 7 was mutagenic and monochloroacetic vinegar is Acid carcinogen. To the quality of t to obtain drinking water, further investigations of chronic di Tetische risk of alachlor degradation products on human health are addressed in the future. By analyzing the fragments obtained in the mass spectra and comparison with data in the literature, has been found that compounds 2, 6 and 9, with 2-chloro acetanilide 2.6 N, 2-chloro-2, were 6 N-diacetyl- acetanilide and 2 2 6 chloroethyl N-acetyl acetanilide. Compound 2 were detected in the direct oxidation of alachlor O3. And some intermediate Detected similar compound 6 and 9were well. The structures of compounds 3 and 5 were in accordance with aniline and 2.6 N 2.6 N diethyl diethyl acetanilide. These compounds have anything similar structures speak with some hunters in the process of biodegradation of acetanilide herbicide. So far, the intermediate layer Similar compound 1, 4 and 7 were not detected in the degradation of acetanilide herbicides. Gem is one of fragments in the mass spectrum speculated structures of compound 1, 4 and 7 are 2,6 diethyl benzenediol, 2-hydroxy-2, 6 N-diacetyl-acetanilide and 2 N acetyl thyltetramethyltetralin acetanilide 6th The retention time of 8 min and was is theMW 24 148 311th It is compatible with the residence time of the L Solution pretilachlor standard. Therefore, the chemical formula of 2-chloro compound 8 to be 2.6 N diethyl acetanilide. Should by the analysis of the fragment of compound 10 in the buy Leflunomide mass spectra, compound 10 hydroxylalachlor that was Similar to the middle of the photocatalytic degradation of alachlor. 3.3. Degradation pathways of pretilachlor In this, the joint opinion of electrocatalysis thattwowayswere oxidation mechanismforDSAelectrode illustrated in the electrochemical oxidation part of organic compounds are: the direct electrochemical oxidation degradation of the electrode and the indirect oxidation of organic compounds with the oxidation product H on the surface surface of the H electrode.When as physical adsorbed oxygen in the surface of the electrode surface down occurs electrochemical combustion of organic compounds and would completely reduced ndig, w during Chemical oxygen adsorbed in the surface of the surface electrodes placed was the electrochemical conversion would be produced, which then causes no degradation of organic compounds incomplete YOUR BIDDING. Cyclic voltammogram was measured to study the direct oxidation of the electric thinking Rpers Sb-doped Ti/SnO2. Fig. 5 shows the CV curves Ti/SnO2 electrode in 0.25 mol L an L solution of sodium sulfate with and without pretilachlor. Peak or no peak observed deoxidized oxidized in the CV curve of an L Solution that pretilachlor, which means that the direct oxidation can occur on the electrode of pretilachlor Surface turns. Under Rutaecarpine terephthalic Acid as an agent H deposition technique was used to test if fluorescence spectrum could H w During the process of electrochemical reduction or not in the previous experiment, our group will be established. The results showed that H was in the surface of the surface electrode Ti/SnO2 need during the electrolysis is produced and H causes the indirect oxidation of the K Rpers.
