Dalton, S.A. Nizkorodov Title: Photochemical Degradation of 4-Nitrocatechol and 2,4-Dinitrophenol in a Sugar-Glass Secondary Organic Aerosol Surrogate Journal/Source: Environ. Sci. Technol., 55, 21, 14586–14594, (2021); https://doi.org/10.1021/acs.est.1c04975 Data: table, diagram Energy/Wavelength range: 235 - 700 nm Resolution: ~ 0.2 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: solution (isopropanol); semisolid isomalt pH: Comments: The goal of this work was to characterize the photolysis of 4-nitrocatechol (4NC) and 2,4-dinitrophenol (24DNP) in semisolid isomalt as a new type of surrogate for glassy organic aerosols and compare it to photolysis in liquid water, isopropanol, and octanol.
