Amoxicillin Degradation by TiO2 P25 Solar Heterogeneous Photocatalysis: Influence of pH and Oxidizing Agent H2O2 Addition

Photocatalytic degradation of amoxicillin, ampicillin and cloxacillin antibiotics in aqueous solution using UV/TiO2 and UV/H2O2/TiO2 photocatalysis

Influence of under pressure dissolved oxygen on trichloroethylene degradation by the H2O2/TiO2 process

BACKGROUND The widespread use of trichloroethylene (TCE) and its frequent release into the environment has caused many environmental and health problems. In this study the degradation of TCE at different micromolar concentrations was investigated in a stainless steel reactor with various concentrations of H2O2 and TiO2 at different oxygen pressures and three different pHs. METHODS To examine ...

Solar Photocatalytic Degradation of Diclofenac by N-Doped TiO2 Nanoparticles Synthesized by Ultrasound

Anatase N-doped TiO2 nanoparticles were synthesized using ultrasound at low frequency and room temperature. The samples characterized by techniques including XRD, TEM, HRTEM, FT-IR, XPS, and UV–Vis spectroscopy. XPS indicated the existence of nitrogen as an anion dopant within the TiO2 lattice. The solar photocatalytic activity of N-doped TiO2 studied for th...

TiO2 photocatalysis

It is known that TiO2 exhibits good photocatalytic properties which could be used in various commercial applications such as water and air purification or photo-induced biodegradation of microbes. TiO2 occurs in nature in the form of three crystal polymorphs: anatase, brookite and rutile. For photocatalytic applications only anatase and rutile are of interest, however anatase shows greater phot...

Oxidation of lindane in contaminated water under solar irradiation in the presence of photocatalyst and oxidizing agents

The oxidation of lindane is investigated by photooxidation and photocatalytic procedures using solar light irradiation. The photocatalyst used in photocatalysis is Degussa P25 TiO2. The degree of oxidation is followed by chemical oxygen demand (COD) measurements. The oxidation process is carried out at different initial concentrations of lindane varying from 0.05×10 M to 1.0×10 M. The photooxid...
