Title: Effect of dissolved oxygen on the photodecomposition of monochloramine and dichloramine in aqueous solution 
by UV irradiation at 253.7 nm

Journal/Source: Water Research, 44 (10), 3261-3269, (2010), doi:10.1016/j.watres.2010.03.009


Data: (diagram, table, disk): diagram

Energy/Wavelength range: 253.7 nm; 220 - 360 nm

Resolution: 

Temperature: 

Temperature dependence: 

Pressure/Concentration: ~ 1.5 - 2 mM

Phase (gas, liquid, solid): aqueous solution

Comments: The apparent quantum yields of photodecomposition of dichloramine (NHCl2 ~ 1.5-2 mM, pH = 3.7 ± 0.2) in oxygen-free 
and in oxygen-saturated solutions were quite identical (PHI = 0.82 ± 0.08 mol E-1).
