Parameter Screening for the Important Factors Influencing the Aniline Removal by Photocatalysis over Supported Zinc Oxide Catalyst

Abstract:

Aniline was removed by photocatalysis reaction using zinc oxide (ZnO, ZnO/Al₂O₃ and ZnO/SiO₂) as catalysts. The oxidation reactions were carried out in a batch reactor. The experiment was designed by Pleckett-Burman Full Factorial Design (FFD) for screening test. The FFD was used to factors screening of 3 factors: wt% of ZnO, catalyst loading and UV light source on aniline removal. The equation model for factors screening was well fitted to the experiment data, which was observed by R²coefficient of 0.95. The results show that wt% of ZnO and catalysts loading were the significant effects. The highest percentage aniline removal of 82.7% was achieved at the reaction condition; 0.5g of ZnO catalyst and 30wt%ZnO under UV-C irradiation. Moreover, it was found that Pleckett-Burman FFD was useful in factor screening of the aniline removal by photochemical reaction over ZnO-based catalysts.
