In this contribution, the photoactivity upon activation by simulated sunlight of zinc oxide (ZnO) obtained from two different synthetic pathways (Acetate and Nitrate) is investigated for water purification. Different reagents processes were exploited to obtain ZnO nanoparticles. Products have been characterized means X-Ray Diffraction, Scanning Electron Microscopy along with Energy Dispersive S...

In the present study, the decolorization and degradation of Reactive Black 5 (RB5) azo dye was investigated by biological, photocatalytic (UV/TiO2) and combined processes. Application of Candida tropicalis JKS2 in treatment of the synthetic medium containing RB5 indicated complete decolorization of the dye with 200 mg/L in less than 24 h. Degradation of the aromatic rings, resulting from the de...

In this study, the halloysite nanotube material will be fabricated from a natural mineral and used as support for photocatalytic activity phase based on TiO2. The is characterized by modern physicochemical methods such XRD, SEM, BET, UV - vis spectrum, EDX. Accordingly, refined has nanoscale with length of about 1.3 μm capillary size 5 nm. After deposition Ag TiO2 halloysite, specific surface m...

In the present study, methylene blue (MB) removal from aqueous solutions via photocatalytic process using TiO2 as a catalyst in presence of external ultra-violet light (UV) was investigated. The results adsorption absence UV radiation showed that reached an equilibrium state at 60 min. experimental kinetic data were found to be well fitted by pseudo-second-order model. Furthermore, isotherm stu...
