Le présent travail porte sur la photodégradation d’un colorant azoté ‘’ l’Orange G‘’  à température ambiante en présence d’une suspension aqueuse de dioxyde de titane.  L’influence de différents paramètres (semi conducteurs de la série PC ‘’Tion... see more

The voluntary or accidental release of chemical compounds in the environment is a major cause of pollution of natural waters. Most of chlorophenols are toxic and hardly biodegradable and are difficult to remove from the environment. Therefore, it is impor... see more

Heterogeneous photodegradation of Linuron under UV irradiation was investigated. Natural iron oxide (NIO) was used in this study, to take a closer look at its adsorption capacity in the dark. The results obtained showed that the substrate photolysis is ve... see more

A heterogeneous photo-Fenton-like degradation process of 1-naphthol (1-NP) promoted by natural iron oxide (NIO) in the presence of H2O2 was studied under artificial (365 nm) and solar irradiation. This is an important reaction for the environment since bo... see more

In this work, the methylene blue (MB) heterogeneous photodegradation was investigated in the natural iron oxide (NIO) and oxalic acid process under UV irradiation. The adsorption of MB onto the surface of NIO was found favorable by the Langmuir approach. ... see more

A natural iron oxide (NIO) was applied for the photodegradation of 2,6-dimethylphenol in presence of polycarboxylic acids under UV irradiation. The dependence of 2,6-DMP degradation was attributable to the formation of dissolved Fe–polycarboxylate in the... see more
