摘要: The use of TiO2 and Zeolite-Y as photo catalytic systems was investigated for adsorption removal methylene blue from aqueous solutions. As first step, the effect pH, time initial concentrations were studied in absence ult ra violet irradiation. Langmuir fruendlich isotherms, second order kinetics used to describe process which occurred UV isotherm found best proce ss. Adsorption done at pH=8 both catalysts completed 30 minutes reach equilibrium concentration. Maximum amount can deposit on surface catalyst be 294.11 mg/g 156.25 Zeolite-Y, respectively. Also results showed that aeration solutions had reverse adsorption. Ultraviolet irradiation started just after reaching process. This led begin immediately 60 minutes. All experiments repeated presence aeration. result fo r pH investigation, Ph = 3 4 pHs by 60% 76%, aeration, These amounts 41% 53% Zeolite.
