Abstract

Heterogeneous photocatalysis process has proven its points of interest over traditional strategies for wastewater treatment. In the present study, the heterogeneous photocatalysis treatment was applied for degradation of the pharmaceutical wastewater of cetirizine by using TiO2 as photocatalyst. The experiments were run in slurry mode. The input parameters which were differed are pH, cetirizine concentration, and TiO2 dose and time. Optimization was performed by using Response Surface Methodology (RSM). At the optimized conditions pH = 3.35 and TiO2 dosage 2.32 g/l, % degradation was observed to be 98.38% for 420 min. Kinetic study showed that degradation of cetirizine follows first-order kinetics with rate constant value k = 0.007 min−1. The RSM results demonstrate that the predictions agreed with the experimental results.
