Photocatalytic Degradation of Phenol

Environmental Monitoring and Assessment, 2003
In this study photocatalytic degradation of phenol in the presence of UV irradiated TiO2 catalyst and H2O2 was investigated. Effects of TiO2 and H2O2 concentrations and pH on photocatalytic degradation were examined. The rate constants for photocatalytic degradation were evaluated as a function of TiO2 and H2O2 concentrations and pH of the solution. It

Photocatalytic degradation of 2,4-dinitrophenol

Journal of Hazardous Materials, 2009
Contamination of the food supply from agricultural waste is an increasing concern worldwide. Numerous hazardous chemicals enter the environment from various industrial sources daily. Many of these pollutants, including 2,4-dinitrophenol (2,4-DNP), are water soluble, toxic, and not easily biodegradable.

Kinetics of the photocatalytic degradation of benzene

Catalysis Today, 2007
The kinetics of photocatalytic degradation of benzene in air has been studied on a standardized micro-pilot scale continuous flow apparatus. Both the yield of conversion of the reactant and the apparition of CO and CO2 have been monitored. The influences of concentration, light flux and temperature on the initial degradation rate have been studied.

A Short Review on Photocatalytic Degradation of Formaldehyde

Journal of Nanoscience and Nanotechnology, 2015
Nowadays, it is a great challenge to eliminate toxic and harmful organic pollutants from air and water. This paper reviews the role of TiO2 as a photocatalyst, light source and photoreactor in the particular case of removal of formaldehyde using the photocatalytic reaction by titanium dioxide (TiO2) in aqueous and gaseous systems.

Photocatalytic degradation of E. coliform in water

Water Research, 2003
This study aims to further investigate the total mineralization of the bacteria to the extent of death and cell-mass inactivation using a TiO2-Fe2O3 membrane photocatalytic oxidation reactor. Experimental results clearly indicated that dissolved oxygen (DO), hydraulic retention time (HRT) and concentration of the model bacteria (Escherichia coliform ...

Photocatalytic degradation for environmental applications – a review

Journal of Chemical Technology & Biotechnology, 2001
AbstractPhotocatalysis is a rapidly expanding technology for wastewater treatment. In this review the chemical effects of various variables on the rate of degradation of different pollutants are discussed in detail. The effects of adsorption, temperature, intensity of light, pH, and the presence of anions, cations, etc have been specifically covered. A

Photocatalytic degradation of phosphamidon on semiconductor oxides

Journal of Hazardous Materials, 2003
The photocatalytic degradation of a small concentration of an organo-phosphorous (OP) insecticide phosphamidon, in water, on ZnO and TiO(2) is investigated. Of the two semiconductor oxides, TiO(2) is found to be more effective as a photocatalyst for this reaction. Several factors such as concentration of phosphamidon, pH of the system, catalyst loading
