Photocatalytic Degradation of Acetaminophen

2011
The photocatalytic degradation of a common analgesic (acetaminophen) with titanium dioxide irradiated with low energy ultraviolet light (365 nm) was studied in order to determine the effect of several parameters such as catalyst’s weight, photochemical effect, and initial concentration.

Photocatalytic degradation of molinate in aqueous solutions

Environmental Science and Pollution Research, 2014
In this study, the degradation of molinate through heterogeneous photocatalysis, using two different types of the semiconductor TiO2 as photocatalyst, as well as through homogeneous treatment, applying the photo-Fenton reaction, has been investigated. As far as heterogeneous photocatalysis is concerned, the degradation of the pesticide follows apparent

Heterogeneous photocatalytic degradation of monochlorobenzene in water

Journal of Hazardous Materials, 2008
This investigation evaluated the photocatalytic degradation of monochlorobenzene (MCB) in an aqueous TiO(2) suspension. In accordance with the experimental results, the degradation of MCB was a function of the initial substrate concentration, incident light intensity, and TiO(2) dosage.

Photochemical and photocatalytic degradation of trans-resveratrol

Photochemical & Photobiological Sciences, 2013
Photochemical and photocatalytic degradation of the emerging pollutant trans-resveratrol has been studied under different irradiation wavelengths and using different TiO2 catalysts. trans-Resveratrol was more easily degraded when irradiated using the whole spectral range (UV-Vis) rather than with UV and near-UV to visible irradiation.

An overview of photocatalytic degradation: photocatalysts, mechanisms, and development of photocatalytic membrane

Environmental Science and Pollution Research, 2019
Photocatalysis is an ecofriendly technique that emerged as a promising alternative for the degradation of many organic pollutants. The weaknesses of the present photocatalytic system which limit their industrial applications include low-usage of visible light, fast charge recombination, and low migration ability of the photo-generated electrons and ...

PHOTOLYTIC AND PHOTOCATALYTIC DEGRADATION OF PHARAMCEUTICALS

2016
Pharmaceuticals are highly diverse group of compounds used for treating and preventing diseases in humans and animals. They are designed to be biologically active and therefore they might negatively affect non- target living organisms. Owing to the advances of different analytical methodologies during the last decade, the widespread occurrence of these

Photocatalytic degradation of para-hydroxybenzoic acid: Relationship between substrate adsorption and photocatalytic degradation

Clean Products and Processes, 2000
Dark adsorption and photocatalytic degradation of para-hydroxybenzoic acid (PHBA) was studied in the presence of Degussa P-25 titanium dioxide photocatalyst under concentrated solar radiation. This work includes the study of the effect of pH, and of the presence of different anions and cations on dark adsorption and photocatalytic degradation (PCD) of ...

Photocatalytic degradation of the diuron pesticide

Environmental Chemistry Letters, 2007
The occurrence of chlorinated pesticides in wellwaters is a major problem of public health in Ivory Coast and other African countries. Here, we studied the photocatalytic degradation of the pesticide diuron in aqueous solution in presence of two commercial TiO2 catalysts, P25 and PC500. The capacity of diuron adsorption at the TiO2 surface is lower for
