TiO2-codoped [FeII(bpy)3]2+/zeolite Y systems are revealed to be efficient photocatalysts for photochemically enhanced Fenton processes. Preparation, characterization, and tests using 2,4-xylidine as a model pollutant are described, and a first mechanistic hypothesis explaining the rather high photochemical reactivity of the

The possibility of using zeolites containing the 2,4,6-triphenylpyrylium cation as photocatalysts for the degradation of pollutants has been tested on aqueous xylidine (2,4-dimethylaniline) solutions as models for contaminated wastewaters. The influence of the photocatalyst and substrate concentrations on xylidine oxidation

Among advanced oxidation processes (AOPs), the photochemically enhanced Fenton reaction may be considered as one of the most efficient for the degradation of contaminants in industrial wastewater. This process involves a series of complex reactions. Therefore, an empirical model based

2,4-Dimethylaniline is a recalcitrant degradant of the pesticide amitraz and is also an industrial pollutant which is genotoxic, teratogenic and carcinogenic. The biological degradation of 2,4-dimethylaniline was examined and monitored by cyclic voltammetry. Pseudomonas species isolated from cattle dip tanks
