A novel iron-containing mesostructured material has been successfully tested for the heterogeneous photo-Fenton degradation of phenolic aqueous solutions using near UV-visible irradiation (higher than 313 nm) at room temperature and close to neutral pH. This catalyst is a composite material that contains crystalline hematite particles embedded into the mesostructured SBA-15 matrix in a wide dis...

in the last twenty years, due to a number of natural and anthropogenic reasons, many water sources have become poorer in quality with respect to micropollutants. an example of a micropollutant that needs to be removed is the chlorophenoxypropionic herbicide mecoprop (mcpp). mcpp is one of the nine pesticides used as an indicator to monitor pesticide concentrations in rivers because it is freque...

ABSTRACT. In this study, the effect of Fenton and photo-Fenton processes, which are advanced oxidation processes that use hydroxyl radical for decolorization Novacron Black from aqueous solutions, on was investigated. Optimum levels initial pH, temperature, hydrogen peroxide concentration, dyestuff iron concentration were determined. Initial Fe2+ most effective experimental parameters in with p...

This study evaluated the COD removal performances of classical-Fenton and photo-Fenton Processes by different prediction models. To optimize both Fenton processes performed in batch reactors, effects H2O2 dose, Fe(II) H2O2/Fe(II) rate, contact time were determined as independent variables Besides response surface methodology, three neural networks used to more reliably effectively predict behav...
