Abstract

In the present study, the photocatalytic degradation of 2,4-DCP has been investigated in a batch reactor under UV light in slurry mode using titania P-25 (surface area 50 m2/g) as a photocatalyst and sodium hypochlorite as an oxidant. Variables studied include catalyst dose, pH and oxidant concentration. The rate of degradation was studied in terms of changes in concentration of the pollutant and reduction in chemical oxygen demand. The optimal values of operational parameters leading to 2,4-DCP abatement were obtained by using response surface methodology.
