Hydrogen Peroxide Photolysis with Different Uv Light Sources including a New Uv-led Light Source
نویسنده
چکیده
Hydrogen peroxide 0.1% was photolyzed using 17W low pressure mercury arc lamp and 125 W high pressure mercury arc lamp. The decomposition kinetics was followed through the pseudofirst order kinetics and different conditions of temperature and pH were explored. H2O2 0.1% was also photolyzed at 360 nm through a new UV-LED 3W light source using a flow reactor. The kinetics rate constant achieved with the UV-LED photolysis is at least one order of magnitude lower than that achieved with the low pressure mercury arc lamp. Other drawbacks of the UV-LED photolysis were evidenced.

Photodegradation of humic acids in the presence of hydrogen peroxide.
A batch photoreactor was used to evaluate the UV/H2O2 oxidation process for the removal of humic acids in water. A 450-W UV lamp with high-pressure mercury vapor was employed as the light source. The residues of humic acids and hydrogen peroxide were measured for assessment of process performance and understanding of process reaction behavior. The UV photolysis alone can play an important role ...

Anionic DBS surfactant can be photodegraded in a TiO2 dispersion and H2O2 solution under an Hg-lamp (15 W) UV illumination or solar exposure. Degradation process has been monitored through cleavage of aromatic moiety. Degradation of the detergent was small when the photolysis was carried out in the absence of TiO2 and H2O2 an...

One of the technological challenges for hydrogen sensors is long-term stability and reliability. In this article, the UV-light irradiation was introduced into the hydrogen sensing process based on water photolysis effect of Pt/WO3. Ascribing to that, fiber optic hydrogen sensor with Pt/WO3 nanosheets as the sensing element was demonstrated with significantly improved performance of stability. U...
متن کاملPhotodegradation of the antibiotic sulphamethoxazole in water with UV/H2O2 advanced oxidation process.
Photodegradation of the antibiotic sulphamethoxazole (SMX) in water using a medium-pressure UV lamp combined with H2O2 (UV/H2O2) was used to generate the advanced oxidation process (AOP). The photodegradation process was steadily improved with addition of H2O2 at relatively low to moderate concentrations (5 to 50 mg L(-1)). However, the addition of H2O2 to the photolysis process at higher conce...
متن کاملWEIGHTED FLUENCE-BASED PARAMETERS for Assessing UV and UV/H2O2 Performance and Transferring Bench-Scale Results to Full-Scale Water Treatment Reactor Models
The lack a of standard approach for presenting contaminant remediation kinetics using the UV/H2O2 advanced oxidation process (AOP) for water treatment hampers efforts to cross-interpret results and apply literature data for the prediction of treatment efficiencies in new experimental settings. Properly weighted UV fluence rates can be used to define parameters for assessing the UV/H2O2 AOP that...
