Title: Modeling the quantum yields of herbicide 2,4-D decay in UV/H2O2 process

Journal/Source: Chemosphere, 44 (5), 935-941, (2001)


Data: (diagram, table, disk): 

Energy/Wavelenght range: 253.7 nm

Resolution: 

Temperature: 

Temperature dependence: 

Pressure: 


Comments: The 2,4-D decay quantum yields under ultraviolet (UV) light at 253.7 nm increased from 4.86 x 10(-6) to 1.30 x 10(-4) 
as the ratio of (H2O2)/(2,4-D) increased from 0.05 to 12.5. The decay of 2,4-D was also pH dependent.
