Palm, C. Zetzsch Title: Investigation of the photochemistry and quantum yields of triazines using polychromatic irradiation and uv-spectroscopy as analytical tool Journal/Source: Intern. J. Environ. Anal. Chem., 65, 313 - 329, (1996); DOI: 10.1080/03067319608045564 Data: table, diagram Resolution: 1 nm Energy/Wavelength range: 200 - 300 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: solution (acetonitrile; hexane; water/5% acetonitrile) pH: 7 - 9 Comments: Photochemical reactions of atrazine, propazine, simazine, terbuthylazine, ametryn and atraton were investigated in aqueous and buffered (pH=7–9) solutions (containing a few percent of acetonitrile). Quantum yields in aqueous solutions for the chlorotriazines (Phi=0.048-0.062) and for ametryn (Phi=0.043) are comparable.
