General description

3-(4-Chlorophenyl)-1,1-dimethylurea is an inhibitor of photophosphorylation. The kinetics of photo-induced transformation of 3-(4-chlorophenyl)-1,1-dimethylurea has been investigated in aqueous solution containing nitrates and nitrites at 310nm and 365nm. Degradation of Monuron (3-(4-chlorophenyl)-1,1-dimethylurea) photoinduced by Fe(III) in aqueous solution has been reported.

A comprehensive study of the degradation of monuron, one of the phenylurea herbicides, was conducted by UV-Vis/WO(3) process. It was found that hydroxyl radicals played a major role in the decay of monuron while other radicals (e.g. superoxide) and hole
