On August 15, 2015, Li, Wei; Liu, Yucan; Duan, Jinming; van Leeuwen, John; Saint, Christopher P. published an article.Computed Properties of 626-48-2 The title of the article was UV and UV/H2O2 treatment of diazinon and its influence on disinfection byproduct formation following chlorination. And the article contained the following:
Incomplete oxidation of organic micro-pollutants may result in diverse, intermittent oxidation byproducts, significantly affecting disinfection byproduct (DBP) formation from the original solutions following chlorination. This work assessed DBP formation from diazinon in solution due to the formation of intermittent oxidation byproducts by UV and UV/H2O2 pre-oxidation Monochloroacetic acid (MCAA), dichloroacetic acid (DCAA), trichloroacetic acid (TCAA), chloroform (TCM), dichloroacetonitrile (DCAN), and 1,1,1-trichloroacetone (1,1,1-TCP) were detected for chlorinated diazinon solutions which were treated by UV and UV/H2O2 oxidation DBP formation significantly increased in diazinon solutions treated by UV irradiation Solution pH and H2O2 dose also had distinct effects on DBP formation, depending on the individual DBP species. Speciation and mol. structures of oxidation byproducts were analyzed by mass spectrometry and tandem mass spectrometry. Four main UV oxidation byproducts (2-isopropyl-6-methyl-4-pyrimidinol [IMP], O-analog diazinon [diazoxon], di-Et thiophosphate [DETP], di-Et phosphate [DEP]) were examined individually to identify their relative contribution to DBP formation. Increased total DBP formation of treated diazinon solutions was mainly attributable to its oxidation product, IMP, and its secondary oxidation products; the other 2 fragments, DETP and DEP, had little effect. Its oxidation fragment, diazoxon, intensified MCAA, DCAA, and TCAA formation under UV/H2O2 pre-oxidation conditions. The experimental process involved the reaction of 6-Methylpyrimidine-2,4(1H,3H)-dione(cas: 626-48-2).Computed Properties of 626-48-2
