Photo catalytic degradation of methylene blue in aqueous solutions using TiO2 nanoparticles
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 12
Abstract
Colored wastewater from dyeing and textile industry is one of the most important sources of environmental pollution. Using appropriate methods to remove toxic pollutants from industrial wastewater is necessary for the environment. In the present study, photo catalytic degradation of Methylene blue in aqueous solutions using nanoparticles of TiO2 was investigated. The effects of operating conditions such as initial dye concentration, solution pH, and catalyst loading and different sources of UV irradiation were investigated. The results revealed that catalyst loading of 0.2 g/l was the optimum and further increase in the TiO2 loading reduced removal efficiency. In addition, higher degradation rate was observed at pH=5. The order of degradation rate using different sources of UV irradiation was shown to be UV-C > UV-A > UV-LEDs.
