Using microwave along with TiO2 for degradation of 4-chloro-2-nitrophenol in aqueous environment

Using microwave along with TiO2 for degradation of 4-chloro-2-nitrophenol in aqueous environment In this project, microwave (MW) irradiation, photolysis, and photo catalyst were used for degradation of 4-chloro-2-nitro phenol (4-C2NP) in aqueous environment. The influence of main operating parameters such as initial pH, initial concentration of 4C2NP, power dissipation and the dosage of TiO2 on the degradation efficiency has been investigated. The optimum conditions was obtained such as initial concentration of 4C2NP at 30 mg L−1, initial pH at 6, power dissipation at 16 W for UV irradiation, and the amount of TiO2 at 0.2 g L−1. The removal of 4C2NP and chemical oxygen demand (COD) after 100 min of reaction in the combined method (MW/UV/TiO2) was obtained as 80.5% and 47.3%, respectively. Almost all processes are followed from the pseudo first order kinetics and the degradation rate of 4C2NP obeyed the following order: UV/TiO2/MW > UV/TiO2 > MW/UV > UV>MW. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals
