In this study, the photocatalytic degradation of two biologically treated textile finishing wastewater was investigated using powdered TiO 2 and ZnO catalysts with UV-A lamp irradiation. Photodegradation and photodecolorization of the samples real textile industrial wastewater is observed directly...

In this study, Kandira stone, extensively used as a cladding material for building stone has been examined for the removal of an antibiotic Ciprofloxacin hydrochloride (CIP) from its aqueous solution. Batch experiments were performed to investigate the adsorption kinetics, equilibrium and...

Cu 2O photocatalyst is synthesized by solvothermal method. Morphology and structure of Cu 2O photocatalyst are analyzed by SEM, XRD and N 2 sorption technique. The catalytic performances and reaction kinetics of Cu 2O photocatalyst for the degradation of methylene blue (MB) are investigated. The...

This paper examines the effect of humic acids (HA) and other solution constituents (Ca 2+, Mg 2+, Na +), frequently encountered in potable water sources, on the removal of a well-known herbicide, atrazine (ATR), by a laboratory-scale pilot Photocatalytic Membrane Reactor (PMR) system. Experimental...

Recently, considerable efforts have been devoted to overcome a major limitation in semiconductor photocatalysis, the recombination of photogenerated e --h + pairs which leads to reduced quantum yields. Considering the impacts of various parameters on the photocatalytic degradation efficiency, our...

The present paper discusses an integrated electrochemical decolorization/degradation treatment procedure of indigo carmine dye, which comprises electrocoagulation, electrooxidation and advanced electrochemical oxidation using the electro-Fenton process. The electrocoagulation process is performed by...

Tubular halloysite clay mineral and nanocrystalline TiO 2 were incorporated in the preparation of nanocomposite films on glass substrates via sol-gel method at 450ºC. The synthesis involves a simple chemical method employing nonionic surfactant molecule as pore directing agent along with the acetic...

Iron oxide materials were synthesized by an easy and rapid hydrothermal method using different iron precursors (FeCl 3∙6H 2O, Fe(NO 3) 3∙9H 2O and K 4Fe(CN) 6∙3H 2O), solution pHs (acid and basic) and reaction times (3 h and 6 h). The synthesized materials were thoroughly characterized by...

The photocatalytic degradation of caffeine has been investigated in aqueous suspensions of titanium dioxide (TiO 2) by monitoring process efficiency at varying TiO 2 (25 - 175 mg l -1) and initial drug concentrations (0.5 - 9.5 mg l -1). The use of the response surface methodology (RSM) allowed to...

Solar simulated heterogeneous photocatalysis (SSHP) with suspended TiO 2 was investigated in the inactivation of tetracycline resistant/sensitive Enterococcus (TRE/TSE) strains in the effluent of an urban wastewater treatment plant (UWTP). The effect of solar simulated disinfection (SSD) on the...
