It was established a pseudo-first order kinetics in respect to DDVP degradation, Cl- release and PO4-3 liberation and calculated their rate constants. It was also showed the role of H2O2 concentration.Oancea PetrutaPetruta Oancea.Photosensitized oxidation of dichlorvos by H2O2. Analele Universitatii...
R Chen,JJ Pignatello - 《Journal of Advanced Oxidation Technologies》 被引量: 13发表: 1999年 Roles of varied radicals in NO oxidation by Fe~(2+)/H_2O_2 system Fe2+/H2O2 system contains a variety of oxidizing free radicals, such as O-2·,·OH and HO2·. In this paper, the behavio...
This process is performed in the presence of oxidants (e.g HCl, HNO3, H2O2, H3PO4) to increase oxygen functionalities. Some electrochemically inert oxygen functionalities can enhance the hydrophilic characteristic of biochar-based electrodes and therefore improve the specific capacitance through ...
An anodic voltammetric wave of NO catalyzed by meso-tetra(N-methyl-4-pyridyl) iron(III) pentachloride ([Fe(TMPyP)]) was found in a phosphate buffer solution (pH 7.4). The current was 10 times larger than the diffusion-controlled current of NO without the iron porphyrin. The current can ...
Additionally, a mild TEMPO-CuCl-catalyzed aerobic oxidation of the primary alcohols type 77 to the corresponding aldehydes 200 in [bmim][PF6] was developed. Remarkably, reactions proceeded with no trace of overoxidation to carboxylic acid (Entry 2, Scheme 81) [2002OL(4)1507]. Sign in to ...
Phenols may be converted by OH/NO2 or NO3 in both gas and aqueous phase.The nitrate radical in aqueous solution may undergo reactions with aromatic compounds which have been shown to proceed faster than the corresponding gas-phase reactions by orders of magnitude. In order to better understand ...

At higher temperatures, O3 decomposed to O2 and O, which resulted in a decrease of the NO conversion rate. When the mole ratio of O3/NO was greater than 1, products with a higher oxidation state (such as NO3, N2O5) were formed. The reactions between O3 and SO2 were weak; as such, ...
These reagents may be used in the presence of UV light, catalyst, ultrasound to advance the oxidation process. AOPs may be classified broadly into four groups: photocatalytic process (H2O2/UV, O3/H2O2/UV, UV/TiO2, H2O2/TiO2/UV, O3/TiO2/UV); the Fenton reaction-based processes (Fe2+/H2O2...
Oxygen combines with the free-radical species to create new reactive species, including peroxy radicals and hydroperoxides (O2+R•→ROO•+RH→ROOH+R•) and other fragment species (H2O, H2, H2O2) • The hydroperoxides (ROOH) in turn are themselves reactive, creating new free-radical spe...
