Visible light irradtion. Phenol photodegradation Langmuir isotherm adsorption ZnFe2O4/TiO2-GAC Abstract The photocatalysts of ZnFe2O4/TiO2-GAC was synthesized by sol-gel method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV/visible absorption spectra and Brunauer-Emmett-Teller (BET).
The experimental study of equilibrium isotherm of ZnFe2O4/TiO2-GAC in phenol solution was investigated and fitted with Langmuir isotherm to obtain the equilibrium constants.
ZnFe2O4/TiO2-GAC photcocatalysts were used to photodegrade phenol under visible light irradiation at different experimental parameters such as stirring speed, reaction temperature, light intensity and chloride ion concentration.
The results show that the best reaction temperature in the phenol photodegradation is 35℃； low light intensity and high chloride ions concentration would decrease the rate of phenol photodegradation.
