The olive oil industry in Palestine is an important and widely spread one and accomplished with the release of large amounts of olive-mills wastewater. This wastewater represents a significant environmental problem due to its high phenolic content. In this work, the photocatalytic degradation of the some phenolic compounds (gallic acid, oleuropein and resorcinol) present in olive-mills wastewater using the synthesized nanoparticles of mixed SnO2-MgO catalyst and solar irradiation was performed. The nanoparticles of mixed SnO2-MgO catalyst with different ratios were prepared by sol gel method using a modified procedure. The obtained particles were characterized by SEM and XRD. The particle size was determined as 4.32 ± 0.42 nm which is much smaller than those previously prepared by standard procedures. The degradation percentage of phenolic compounds was measured by UV spectrophotometry. The effect of time, catalyst amount and phenolic compound concentration on degradation efficiency was studied. The maximum degradation was achieved using SnO2-MgO (4:1) catalyst, 2.5 mg catalyst per 5 mL solution, within the time of 60-120 min and ranged from 51 to 90 % for different concentrations of phenolic compounds.Keywords: Photocatalytic degradation, Olive mill wastewater, Gallic acid, Resorcinol, Oleuropein.Asian Journal of Chemistry; Vol. 30, No. 9 (2018), 1994-1998 This is an open access journal, and articles are distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) License, which allows others to copy and redistribute the material in any medium or format, remix, transform, and build upon the material, as long as appropriate credit is given and the new creations are licensed under the identical terms.

Nanoparticles were found having applications in various fields of life but recently in diagnostic and therapeutic fields of medicine. Iron oxide-tin oxide (Fe 2 O 3 -SnO 2 ) nanoparticles were synthesized via hydrothermal method with various concentrations of sodium dodecyl sulfate (SDS) surfactant. Their characterization was done by Fourier Transform Infrared Spectroscopy (FT-IR), Thermogravimetric Analysis (TGA), Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) powder techniques. Antibacterial activities of these metal oxides nanoparticles were determined and they were found active against gram-positive B. subtilis and B. lichniformis and gram-negative E. coli, P. aeruginosa and K. pneumonia.

“…[15][16][17][18][19]. Among them, sol-gel method offers several advantages over other methods such as high purity, better homogeneity, phase-pure powders at a lower temperature, ability to control the grain size, and capability in controlling the textural and surface properties of metal oxides.…”

In this study, pure and Co-doped tin oxide (SnO 2 ) nanoparticles were synthesized by sol-gel method, and the effect of Co-doping on the structural, optical, photocatalytic, and antimicrobial activities was studied. The prepared samples were characterized by X-ray diffraction (XRD), highresolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, UV-visible diffuse reflectance spectroscopy, and N 2 adsorption/desorption analysis. The XRD patterns of all the samples are identified as tetragonal rutile-type SnO 2 phase which is further confirmed by TEM analysis. The optical spectra showed redshift in the absorption edge of doped samples, which enhances their absorption toward the visible light region. The photocatalytic activity of all the samples was assessed by monitoring the degradation of methylene blue solution under daylight illumination, and it was found that the photocatalytic activity significantly increases with the increase in dopant concentration, which is due to the effective charge separation of photogenerated electron-hole pairs. The antimicrobial studies investigated against standard bacterial and fungal strains showed enhanced antimicrobial activity in doped samples, which can be attributed to the production of reactive oxygen species and large surface area of the nanoparticles.
