摘要：

The effect of heat attachment method parameters such as: sonication time, dosage of catalyst, immobilization temperature and type of solvent were investigated for enhancement of photocatalytic activity of immobilized ZnO nanoparticles on glass plate. Photocatalytic activity of immobilized ZnO was tested in the removal of C.I. Acid Red 88 (AR88) as a model contaminant from textile industry. Results indicated that sonication time, dosage of catalyst and immobilization temperature were very effective on photocatalytic activity of immobilized ZnO oil glass plate and using ethanol instead of water at preparation of immobilized ZnO did not show any considerable effect. In another step, the effect of operational parameters such as light intensity and initial concentration of AR88 on the removal of AR88 were investigated with immobilized ZnO on glass plate. Results indicated that removal rate decreased with increasing initial concentration of AR88 but increased with increasing UV light intensity. (C) 2009 Elsevier B.V. All rights reserved.
