Title: Photochemical reactions of metamitron

Journal/Source: Chemosphere, 35, 1117-1130, (1997); http://dx.doi.org/10.1016/S0045-6535(97)00176-8


Data: table, diagram

Energy/Wavelength range: 200 - 371

Resolution: 1 nm

Temperature: 298 

Temperature dependence: no

Pressure/Concentration:

Phase: aqueous solution

pH: 4; 7; 9


Comments: Quantum yields found in water and at pH=4 and 9 are comparable (Phi = 0.014-0.018) and at pH=7 about a factor of 2 higher, 
probably influenced by the phosphate buffer used.
