“…The study of removal of Acid Orange 7 from aqueous solution by UV irradiation in the presence of ZnO nanopowder was carried out by Daneshvar et al (2007) found that the photodegradation efficiency increased with an increase in ZnO nanopowder concentration. Akyol et al (2004) examined the effect of ZnO loading in decolorization of Remazol Red RR and found that decolorization efficiency of Remazol Red RR increased by increasing the catalyst loading.…”

The direct h + oxidation is therefore suggested to be the main mechanism causing the MR degradation in the present photocatalysis system.…”

La 0.7 Sr 0.3 MnO 3 (LSMO) nanoparticles were synthesized by a polyacrylamide gel route. LSMO-graphene nanocomposites were fabricated by mixing LSMO nanoparticles and graphene into absolute ethanol solution followed by thermal drying. SEM observation shows that the synthesized LSMO nanoparticles are uniformly and regularly shaped like spheres with an average size of ³24 nm. TEM observation reveals that LSMO nanoparticles are well assembled onto graphene sheets. The photocatalytic activity of prepared samples was evaluated by degrading methyl red (MR) under visible-light irradiation. It is demonstrated that LSMO-graphene nanocomposites exhibit an enhanced photocatalytic activity compared to bare LSMO nanoparticles. This can be explained by the fact that the photogenerated electrons are captured by graphene, leading to an increased availability of holes for the photocatalytic reaction. The direct hole oxidation is suggested to be the main mechanism toward the dye degradation.

Photochemical oxidation of methyldiethanolamine (MDEA) in aqueous solution by UV/K2S2O8 process

Methyldiethanolamine (MDEA) as an organic material is a hazardous contaminant in the aquatic environment because of its adverse effects on aquatic life, environment, and humans. In this study, a batch reactor of ultraviolet (UV) light and peroxydisulfate was performed to investigate the degradation of MDEA in aqueous media. The effect of different experimental parameters such as UV irradiation, peroxydisulfate concentration, MDEA concentration, temperature, and solution pH on removal of MDEA was evaluated precisely. No significant degradation was observed with a separate UV light. Adding peroxydisulfate to the solution increased the removal performance more than 75 %.
