background: titanium dioxide (tio2)-mediated photocatalysis has been found to be an efficient method of water treatment and is capable of degrading a wide range of organic pollutants and microbial agents with high efficiency. the microorganism pseudomonas aeruginosa is resistant to chemicals and uv irradiation. bacteria which are resistant to uv-induced oxidative damage of the cell membrane are...

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...

ZnO and SnO2-doped ZnO nanoparticles were prepared by a sol–gel method for the first time. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the ZnO and SnO2-doped ZnO samples. Advanced oxidation processes (AOPs) have proved very effective in treatment of the various hazardous organic pollutants such as surfactants and pharmaceuticals...

introduction: antibiotics as a  type of pharmaceutical compounds are widely used in modern medicine and veterinary industries. they enter the environment in different ways, including agricultural runoff, direct discharge of urban wastewater treatment or human waste, direct disposal of medical, veterinary industrial waste and etc. antibiotics have been able to influence the microbial population....

−Landfill leachate is a toxic effluent of a decomposing landfill that is produced when rainwater percolates through the landfill leaching out contaminants and pollutants. Untreated leachate is a potential source for the contamination of soil, surface and ground water. In this study, the treatment processes such as granular activated carbon (GAC) adsorption/bio-sorption (batch), and advanced oxi...
