Keen, K.G. Linden Title: Degradation of Antibiotic Activity during UV/H2O2 Advanced Oxidation and Photolysis in Wastewater Effluent Journal/Source: Environ. Sci. Technol., 47 (22), 13020-13030, (2013); DOI: 10.1021/es402472x Data: table, diagram Energy/Wavelength range: 200 - 320 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: aqueous solution pH: Comments: This study demonstrates the effect of UV photolysis and UV/H2O2 advanced oxidation on transformation of 6 antibiotics, each a representative of a different structural class, in pure water and in two different effluents and reports new or confirmatory photolysis quantum yields and hydroxyl radical rate constants.
