Abstract
The photocatalysed degradation of a herbicide derivative, N,N-Dimethyl-α-phenyl benzene-acetamide (Diphenamid, 1) has been investigated in aqueous suspensions of titanium dioxide (TiO2) by monitoring the depletion in total organic carbon (TOC) content as a function of irradiation time under a variety of conditions. The degradation kinetics were studied using different parameters such as pH, substrate and photocatalyst concentration, different kind of titanium dioxide and in the presence of electron acceptors such as H2O2, KBrCb and (NH4)2S2O8 besides molecular oxygen. The photocatalytic activity was found to be better for Degussa P25 as compared to other photocatalysts. The photodegradation of the model compound was also carried out under sunlight and its efficiency was compared with that of artificial light source. From the obtained data a detailed account of the influence of various parameters on the mineralization rate have been discussed. The degradation products were analyzed by GC/MS technique and the probable pathways for the formation of different products have been proposed.
