Optimization of Nano-TiO𝟐 Photocatalytic Reactor for Organophosphorus Degradation

Optimization of Nano-TiO𝟐 Photocatalytic Reactor for Organophosphorus Degradation

The photocatalytic decontamination of triethyl phosphate (TEP) is studied by the UV/nano-TiO2 process. The nano-TiO2 concentration and pH value for the complete oxidation of TEP were investigated in different concentrations of TEP. The kinetic reaction was calculated for TEP as a function of initial...

Box 15875-4413, Tehran, IranDepartment of Civil Engineering, University of Science and Technology, Tehran, IranDepartment of Polymer Engineering, Islamic Azad University, Omidiyeh Branch, Khuzestan, IranThe photocatalytic decontamination of triethyl phosphate (TEP) is studied by the UV/nano-TiO2 process. The nano-TiO2 concentration and pH value for the complete oxidation of TEP were investigated in different concentrations of TEP. The kinetic reaction was calculated for TEP as a function of initial concentration of TEP. Results of adsorptions showed that TEP was adsorbed better in alkalinity pH, and the natural pH had the highest reaction rate for complete degradation. Also, the zero-kinetic order with the lag time as a function of initial concentration of TEP and TiO2 was suggested for oxidation of TEP. The optimized concentration of nano-TiO2 was 400 mg/lit which had the best conversion and the lowest lag time in the reaction.http://dx.doi.org/10.1155/2012/510123
