Plumlee, M. Reinhard Title: Photochemical Attenuation of N-Nitrosodimethylamine (NDMA) and Other Nitrosamines in Surface Water Journal/Source: Environ. Sci. Technol., 41 (17), 6170-6176, (2007); DOI: 10.1021/es070818l Data: diagram, table Energy/Wavelength range: 230 nm; 337 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: aqueous solution pH: Comments: The aqueous photolysis of seven alkyl nitrosamines was studied by irradiation in a solar simulator. The quantum yield for NDMA was determined to be PHI = 0.41 and PHI = 0.43-0.61 for the other nitrosamines. Molar absorptivity maxima measured for seven nitrosamines at two absorption bands are listed. Author to whom correspondence should be addressed: (e-mail address):
