Abstract

Successive impregnation and calcination process was performed in order to produce TiO 2 /perlite composites. 2 3-1 fractional factorial design was first applied to optimize the production conditions of TiO 2 /perlite photocatalysts. Seven TiO 2 /perlite composites (including three central point experiments) were produced by manipulating three process parameters (amount of TiO 2 used in impregnation process, particle size of perlite and calcination temperature). Prepared TiO 2 /perlite photocatalysts were characterized by X-Ray Diffraction Spectrometer and SEM. XRD patterns indicated that anatase was the main crystalline phase for all produced samples. Degradation capacities of produced TiO 2 /perlite composites were investigated in methylene blue degradation process. The linear models of TiO 2 loading (%) and methylene blue degradation (%) of TiO 2 /perlite composites were developed by regression analysis of the experimental data. As a result of analysis of variance, it was found that developed models were statistically significant with the p-value of 0.0040 and 0.0003, for TiO 2 loading (%) and methylene blue degradation (%), respectively. According to the coefficient of determination (0.9821 and 0.9970 for the models of TiO 2 loading and methylene blue degradation, respectively) and error analysis, developed models fit well to the experimental data. Effect of process parameters was investigated by using response surface plots. Amount of TiO 2 and particle size were found as the most effective parameters on both TiO 2 loading (%) and degradation efficiency (%). Calcination temperature did not affect TiO 2 loading but methylene blue degradation capacity.
