Photo-Fenton Process for Decolorization of Azo Dye Acid Yellow 23 from Aqueous Solutions by Using ZnO/Clinoptilolite: Optimization and Kinetic Study

ZnO is a wide-bandgap semiconductor having many applications,such as being a photocatalyst, transducer, varistor, phosphor, and transparent conductor [1], and wide varieties of synthesis techniques have thus been developed to produce this material in different forms [2]. They are, for instance, sol–gel process [3], hydrothermal process [4], chemical vapor deposition [5], and solution deposition [6].in this work we supported ZnO on Iranian natural zeolite (Clinoptilolite) and study photocatalytic efficiency for photocatalytic decolorization of azo dye Acid Yellow23 from aqueous solutions by using Fenton reaction in a Batch Photoreactor and then study kinetic of this reaction.
