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.

The impact of 2,4-dinitrophenol and chlorophenyl dimethylurea on ATP content, carbon fixation, O2 evolution, nitrogenase activity and Cr uptake of Anabaena doliolum has been studied. 2,4-Dinitrophenol has been found to be more toxic than chlorophenyldimethylurea for all these processes. However

The immobilization of cobalt ion on different media to catalyze oxone has been investigated. A probe herbicide, Monuron, was effectively degraded by using Co2+/oxone systems. For Co2+ supported on zeolite, 100% of Monuron could be removed within a 10 min

The photodegradation of monuron (3-(4-chlorophenyl)-1,1-dimethylurea) in aqueous solutions under simulated solar irradiation has been conducted by different advanced oxidation processes (UV/H(2)O(2), UV/H(2)O(2)/Fe(2+), UV/H(2)O(2)/TiO(2), UV/TiO(2), dark H(2)O(2)/Fe(3+)). The degradation rates were always higher for the homogeneous catalysis in photo-Fenton reactions (UV/H(2)O(2)/Fe(2+))
