Abstract EN
The titanium dioxide (TiO2) photoassisted degradation of herbicide dinoseb has been examined in aqueous suspensions under UV light irradiation.
The degradation kinetics were studied under various conditions such as substrate concentration, type of catalyst, catalyst dosage, pH, and light intensity as well as in presence of electron acceptors such as hydrogen peroxide, potassium bromate, and potassium persulphate under continuous air purging, and the degradation rates were found to be strongly influenced by these parameters.
The Degussa P25 was found to be more efficient photocatalyst as compared to other photocatalysts tested.
Dinoseb was found to degrade efficiently in acidic pH and all the electron acceptors studied enhanced the degradation rate.
The results manifested that the photocatalysis of dinoseb followed pseudo-first-order kinetics.
A qualitative study of the degradation products generated during the process was performed by GC-MS, and a degradation mechanism was proposed.
