Abstract:

A self-designed reaction device was used as a promising equipment to investigate the oxidation characteristics and kinetics of rosin pentaerythritol ester (RPE) under UV irradiation. Photo-oxidation kinetics and the initial quantum yield (Φ) of RPE were calculated. The initial oxidation product of the photo-oxidation reaction—peroxide was analyzed by iodimetry. The peroxide concentration is related to the light intensity (I) and the temperature (T), and the increasing T and I would destabilize the RPE by accelerating peroxide forming. Photo-oxidation of RPE follows the pseudo first-order react

Emission control of methane from landfills has received considerable attentions in recent years. Photo-electro-catalytic oxidation of methane was carried out at the mode of continuous electrolysis and intermittent illumination with TiO2-coated titanium mesh plate as pholocatalyst and electrode in combination with ionic liquid as electrolyte under UV light irradiation. The result showed that the rapid conversion of methane was achieved under ambient pressure and temperature through photocatalytic oxidation combining with electrolysis.

With the increasing number of recalcitrant pollutants in wastewater treatment plants, there will be a stringent need for rapid and convenient development of tertiary treatment processes such as advanced oxidation processes (AOPs).

Despite the considerable potential of these devices, they have been mostly used for catalyst screening or pseudo-first order kinetics determination, not allowing for knowledge transfer across scales.

Water oxidation is an important reaction that produces electrons and protons, which are important for downstream reactions such as hydrogen production and carbon dioxide reduction. Presently, the slow water oxidation is a key limiting factor for the development of hydrogen production and/or carbon dioxide reduction into practical solar energy storage technologies. An important reason for the slow progress in solve water oxidation problems is the lack of knowledge on the detailed mechanisms by which water is oxidized.

More rapid and effective 4EP degradation was obtained with H2O2/Fe3O4/UV than Fenton-like (H2O2/Fe3O4) and UV/H2O2, which is due to the larger production of hydroxyl radicals from the chemical and photolytic decomposition of H2O2. The operational conditions were varied during 4EP degradation experiments to evaluate the effects of pH, catalyst, concentration, and temperature on the kinetics and efficiency of H2O2/Fe3O4/UV oxidation.

Abstract:

The degradation of Toluidine Blue dye in aqueous solution under UV irradiation is investigated by using photo-Fenton oxidation (UV/H2O2/Fe+). The effect of initial dye concentration, initial ferrous ion concentration, pH, initial hydrogen peroxide dosage, and irradiation time are studied. It is found put that the removal rate increases as the initial concentration of H2O2 and ferrous ion increase to optimum value ,where in we get more than 99% removal efficiency of dye at pH = 4 when the [H2O2] = 500mg / L, [Fe + 2 = 150mg / L]. Complete degradation was achieved in the relatively short time of

Abstract:

This work investigated the application of a solar driven advanced oxidation process (solar photo-Fenton), for the degradation of antibiotics at low concentration level (mg L<sup>-1</sup>) in secondary treated domestic effluents at a pilot-scale. The examined antibiotics were ofloxacin (OFX) and trimethoprim (TMP). A compound parabolic collector (CPC) pilot plant was used for the photocatalytic experiments. The process was mainly evaluated by a fast and reliable analytical method based on a UPLC-MS/MS system. Solar photo-Fenton process using low iron and hydrogen peroxide doses ([Fe<sup>2+</sup

Abstract:

The industrial synthesis of H2O2 is based on the anthraquinone auto-oxidation process, which requires high-energy consumption and an expensive metal catalyst. Solar photocatalysis has been suggested as a green and sustainable process to produce H2O2. Although there have been significant advances in material design to improve the H2O2 production efficiency, the photocatalytic H2O2 production performance remains insufficient to meet industrial demands. In this study, we designed a new reaction environment using aryl alcohol as an organic photo-oxidation substrate. With a metal-free covalent tria

Abstract This work aimed to evaluate the thermal and photo stability of the antioxidant potential (AP) of the Spirulina platensis biomass. Thermal stability was established at 25ºC, 40ºC and 50ºC for 60 days, in the dark, protected from light. Photo stability was evaluated using UV (15 W, λ = 265 nm) and fluorescent (20 W, 0.16 A, power factor FP > 0.5, 50/60 Hz, 60 lm/w, 1200 lm) light for 90 days in capsules, glass and Petri dishes, at room temperature. The AP of the biomass in these conditions was determined at intervals (every 7 and 30 days in the studies of thermal and photo stability,

Abstract:

High efficiency, low pressure mercury vapour lamps producing radiation at the wavelengths of 254 plus 185 nm and 254 nm only, were used to investigate the H2O2 enhanced photo-oxidation of natural organic matter (NOM). NOM is a problem in drinking water for a number of reasons: aesthetics; it provides an energy source for the growth of microorganisms in the distribution system; and reacts with chlorine to produce potentially harmful disinfection by-products. One promising oxidant for the removal of NOM from drinking water is the hydroxyl radical. The aim of this work was to investigate the kine

Abstract:

The resistance of some compounds to conventional treatments engenders the search for alternative methods, such as photo-oxidation. Antibiotics and photo-producers are found in the environment, indicating that these compounds are persistent. This work had as its goal to investigate the photo-oxidation of the antibiotic named tetracycline hydrochloride adsorbed in montmorilloniteclay (VHS) and into aqueous suspension. In order to irradiate the interaction products 0,03g were weighed and put in a petri dish to be collected on pre-determined times. The extraction of the drug was made by adding 10
