Water pollution by organic pollutants has been a growing global problem in recent years, for which there is a great demand of efficient technologies for wastewater treatment. Remediation of water by photocatalytic oxidation has several advantages over adsorption or any other conventional techniques. This study reports a easy synthesis technique of a sulfur doped hollow TiO2 nanocatalyst for pho...

The photocatalytic degradation of gaseous toluene was investigated on TiO2 nanoparticles coated on reduced graphene oxide. Reduced graphene oxideTiO2 composite (RGO-TiO2) was synthesized via two step processes. The prepared RGO-TiO2 composite was characterized using SEM, XRD, and UV-visible spectra. A significant increase in light absorption to visible light was observed by RGO-TiO2 compared wi...

In this study, photocatalytic degradation of diazinon was investigated using commercial nano-TiO2as a photocatalyst the operational parameters such as adsorption, aeration, pH and nano-TiO2 dosage were investigated. Dispersive liquid-liquid microextraction (DLLME) technique was used to extract and preconcentration of residual diazinon and by-products from the liquid samples and the analysis was...

background: heavy metals in aquatic systems usually interfere with many beneficial uses of water. divalent nickel is a commonly occurring toxic metal in natural ecosystems due to the effluent of refineries, electroplating, and casting industries. in aquatic environments, nickel appears as ni (ii) and ni0. despite the high reported toxicity for ni (ii), ni0 is only slightly toxic. various method...

The photocatalytic degradation of Diamond green B, a triarylmethane dye, has been investigated in aqueous heterogeneous solutions containing TiO2 nano- particles as photocatalysts. The factors effective on the degradation of Diamond green B, such as the amount of catalyst, the original concentration of dye, the effect of pH and illumination time were investigated under 400 W high pressure mercu...
