THE INFLUENCES OF Fe(III) ION and Fe(OH)3 COLLOID ON THE PHOTODEGRADATION of p-CHLOROPHENOL CATALYZED BY TiO2

open access: yesIndonesian Journal of Chemistry, 2010
The influences of ionic Fe(III) and colloidal Fe(OH)3 on the effectiveness of p-chlorophenol photodegradation catalyzed by TiO2 has been studied. Photodegradation was carried out in a batch system by irradiating a suspension of TiO2, p-chlorophenol, and ...

Photochemical pathways of 8-oxo-2′-deoxyguanosine under photodegradation

open access: yesAIP Advances, 2022
The common product of an oxidatively damaged DNA, 8-oxo-2′-deoxyguanosine (8-oxo-dG), is known for photorepairing cyclobutane pyrimidine dimers. This study is to uncover the dynamics of 8-oxo-dG under photodegradation, which are poorly understood.
