Increasing photoactivity of titanium dioxide immobilized on glass plate with optimization of heat attachment method parameters

In the present work the optimization of heat attachment method for increasing photoactivity of immobilized TiO(2) on glass plate was investigated. Results show that sonication time, TiO(2) suspension dosage, immobilization temperature, solvent type and immobilization replications are very effective on the photoactivity of immobilized TiO(2) on glass plate on the removal of C.I. Acid Red 88 (AR88) and optimizing these parameters increases the photoactivity of immobilized catalyst. In other step, the effect of operational parameters such as light intensity and initial concentration of AR88 on the removal of AR88 was investigated with four times immobilized TiO(2) on glass plate. Results show that removal rate decreases with increasing initial concentration of AR88 but increases with increasing W-light intensity. (C) 2008 Elsevier B.V. All rights reserved.
