摘要: Abstract In this study nano-composite MWCNT/TiO2 as catalyst is synthesized by a modified sol–gel method and photo-catalytic removal of 2,4-dichlorophenol (2,4-DCP) has been studied in fluidized bed reactor, which designed constructed, under UV solar irradiation. The effects important parameters such as: type catalyst, composition, pH, initial 2,4-DCP concentration, time have investigated on the rate 2,4-DCP. concentrations were measured function irradiation through UV–vis spectrophotometer. Different analysis PSA, FTIR, XRD, conducted to characterize nano-composite. results showed significant dependence functional parameters. demonstrated that with weight component percent 60–40 had best removal. ambient temperature, optimum pH 11 120 min period radiation 87% 93%.
