Photocatalytic Degradation of Ethylene Dichloride in Water Using Nano TiO2 Supported on Clinoptilolite as a Photocatalyst
In this article one of the advanced oxidation processes (AOP) combined methods,photocatalyst /H2O2,is utilized in order to study photodegradation of ethylene dichloride (EDC) in water.Nano Titanium (Ⅳ) Oxide,supported on Clinoptilolite (CP) (Iranian natural zeolite) using solid-state dispersion (SSD) method for improvement of its photocatalytic properties.The results show that the TiO2/Clinoptilolite (SSD) is an active photocatalyst.The effects of five important photocatalytic reaction parameters including the initial concentration of ethylene dichloride,the ratio of TiO2/Clinoptilolite,the catalyst concentration,H2O2concentration and pH in photodegradation of ethylene dichloride were examined.In this experiments,the design and also the optimum parameters were obtained by Taguchi Method,using Design Expert8(R) software.Taguchis L27 (5^3) orthogonal array design was employed for the experimental plan.Four parameters were found to be significant whereas,pH was found to be an insignificant parameter after conducting experiments.A first order reaction with K =0.007 min-1 was observed for the photocatalytic degradation reaction.
