Titanium dioxide remains one of the most studied semiconductor for photocatalytic applications due to its low cost production, reduced toxicity, ability break down organic pollutants and possibility achieve complete mineralization. In this work, we report on results activity titanium nanotubes fabricated by electrochemical anodization technique in an electrolyte solution containing a mixture hy...

Photocatalytic reactor models incorporating radiation transport parameters and intrinsic kinetic of photocatalytic decomposition single-compound mixtures oxalic (OA) formic acid (FA), in both slurry suspensions immobilized thin films, were validated two well-mixed annular photoreactors geometries irradiated with either UVA or UVC radiation. The six-flux absorption scattering model (SFM) predict...

One of the important environmental challenges 21st century is effective removal pollutants from aquatic environment. In this study, electrodeposited manganese oxides (MnyOx) films were applied as visible-light-driven photocatalyst for and mineralization Tetracycline (TC) antibiotics. The photocatalytic activity as-deposited annealed MnyOx was tested at different pH values using LED visible illu...

The synergistic effect of the photocatalytic ozonation process (PH-OZ) using photocatalyst TiO2 is usually attributed to influences physicochemical properties catalyst, pollutant type, pH, temperature, O3 concentration, and other factors. It also often claimed that good adsorption on surface beneficial for occurrence synergism. Herein, we tested these assumptions by five different commercial ph...

Laundry detergent wastewater is a potential renewable resource that can be recycled and reused in order to mitigate water scarcity. The treatment of laundry very challenging because its multicomponent composition, large discharge volumes the environment resulting from increasing usage as global population grows, ineffectiveness conventional technologies. Ozonation one most effective advanced ox...

The problem of textile dye pollution has been addressed by various methods, mainly physical, chemical, biological, and acoustical. These methods mainly separate and/or remove the dye present in water. Recently, advanced oxidation processes (AOP) have been focused for removal of dye from waste water due to their advantages such as ecofriendly, economic and capable to degrade many dyes or organic...

In the present study, photocatalytic removal of p-nitrophenol has been carried out in the presence of ZnO by using a batch reactor with a UV-C lamp (15 W). The effects of applied ZnO concentration and UV light intensity have been studied. The increase of initial pollutant concentration decreases the removal rate, and the results indicate that the apparent reaction rate constant in the UV/Zn...
