Kinetics of photocatalytic degradation of diuron in aqueous colloidal solutions of Q-TiO2 particles

Radiation-induced reduction of diuron by gamma-ray irradiation

“…According to the analysis of LC-MS, R6, R8, R11, R13 and R14 as degradation products were produced, which was in accordance with the previous studies [10,15]. R2 was possibly produced by the attack hydroxyl radical on the aromatic ring of R8, with subsequent loss of two chlorine atoms.…”

“…Diuron could be completely mineralised by electrochemical technology and passivation of the electrode surface was not observed [7]. Photocatalytic methods and photo-Fenton were used by many researchers to remove diuron [1,[8][9][10][11][12][13][14][15][16][17][18]. 100% of chlorine could be recovered as chloride and 90% of mineralization was reached.…”

Gas–liquid hybrid discharge-induced degradation of diuron in aqueous solution

“…Furthermore, diuron is a considered priority substance by the European Union Water Framework Directive (Directive 2000/60/EC) [6]. Several advanced oxidation processes (AOPs) such as electrochemical method, photocatalytic oxidation, photo-Fenton and photocatalytic ozonation have been investigated for diuron degradation [7][8][9][10][11][12][13][14].…”

Adsorption and Photochemical Behaviour of the Herbicide Monuron on Clay Surfaces

“…In the latter case, the formation of the final product can be explained by oxidation of the methyl group to aldehyde function-N (CH3)2. This mechanism has been demonstrated in the most studied of phenylurea herbicides transformation (Macounova et al, 2003). It has been characterized as a majority path in the mechanism of photodegradation of aqueous monuron (Mest'ankova et al, 2004).…”
