Photocatalytic Degradation of Diclofenac
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2013, Vol 3, Issue 3
Abstract
In the present study, photocatalytic degradation of diclofenac (DCF), a non-steroidal anti inflammatory drug was investigated using various photocatalysts. The efficiency of degradation was quantified by several parameters such as effect of initial concentration, catalyst loading, agitation and addition of H2O2 as a co-oxidant. The degradation was measured in terms of UV absorbance at 276 nm. It was observed that in comparison to TiO2, ZnO and Ag-doped TiO2 exhibited higher rate of degradation. The degradation was found to follow first order kinetics. On optimization of various parameters it was found that Ag doped TiO2 (2 mol % loading) could bring about almost complete degradation within 180 minutes for an initial concentration of 20ppm of the drug and at a catalyst loading of 1 g l -1. Addition of hydrogen peroxide as a co-oxidant further enhanced the degradation rate.
