Application Photocatalysis for Treatment of Industrial Waste Water—A Short Review
TL;DR: In this article, a comprehensive review has been presented to deliver essential information about dealing with photocatalytic mineralization of pollutants, and different possible routes of effluent treatment have been reviewed.
Journal ArticleDOI
Kinetic Studies on Black Light Photocatalytic Ozonation of Diclofenac and Sulfamethoxazole in Water
TL;DR: In this paper, the authors studied the competition between direct ozonation and hydroxyl radical oxidation to eliminate sulfamethoxazole (SMX) and diclofenac (DCF) and the resulting total organic carbon (TOC) was studied.
Journal ArticleDOI
Kinetic study of spiramycin removal from aqueous solution using heterogeneous photocatalysis
TL;DR: In this paper, the effect of some key parameters is investigated under low energy of artificial UV light, and the Langmuir-Hinshelwood (L-H) model is successfully used to fit the experimental data, indicating the dependence of the reaction rate on the chemical reaction step.
Journal ArticleDOI
Antimicrobial activity against Gram-positive and Gram-negative bacteria during gatifloxacin degradation by hydroxyl radicals.
TL;DR: The hydroxyl radicals formed in the processes were able to degrade the fluoroquinolone and remove the antimicrobial activity from the aqueous solution and acute toxicity assays showed that the toxicity of the treated solution for V. fischeri increased as the gatifloxacin concentration in the solution decreased.
Journal ArticleDOI
Microcystin-LR degradation by solar photo-Fenton, UV-A/photo-Fenton and UV-C/H2O2: a comparative study.
TL;DR: The kinetic study indicated that the solar photo-Fenton and artificial radiation (UV-A) processes were very similar in their efficiency, and the use of sunlight instead of artificial UV radiation significantly reduced the cost of photocatalytic treatment systems.

TiO2 photocatalysis and related surface phenomena
TL;DR: The field of photocatalysis can be traced back more than 80 years to early observations of the chalking of titania-based paints and to studies of the darkening of metal oxides in contact with organic compounds in sunlight as discussed by the authors.
