Photo catalytic degradation of acrylonitrile in aqueous solutions using nano titanium Dioxide
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 12
Abstract
In the present study, photocatalytic decomposition of Acrylonitrile (ACN) using nano titanium dioxide was investigated. The effects of influential parameters such as ACN initial concentration, solution pH, catalyst loading, inorganic salts and the type of light sources on the reaction rate were evaluated, and optimum conditions were determined. The results of experiments showed that catalyst loading of 0.1 g/l TiO2 was the optimum and further increase in the TiO2 loading reduced removal efficiency. The highest photodegradation reaction rate was obtained in slightly alkaline condition rather than neutral or acidic condition. The experimental data showed that the photocatalytic degradation of ACN can be simulated by using pseudo-first-order reaction rate expression. It was concluded that photocatalytic process offers an interesting prospect for its application to the treatment of wastewater streams containing ACN.
