Bacterial inactivation and study of damages in subcellular level during disinfection of aqueous samples
(Corresponding) Gounaki I., Lironi M., Venieri D.
Topic:
Advanced oxidation processes
The objectives of the current study were i) to investigate the effectiveness of ozonation and UVA photocatalysis for the inactivation rate of representative bacterial strains, which are considered important for public health and ii) to study damages in subcellular level, in terms of disinfection...Read more
Micro-pollutants, Oxidants, Catalysts and the Water Matrix: A Harmonic Quartet or the War of the Roses?
(Corresponding) MANTZAVINOS D.
Topic:
Advanced oxidation processes
Advanced oxidation processes (AOPs, e.g. heterogeneous and homogeneous photocatalysis, electrochemical oxidation, ozonation, ultrasound irradiation, Fenton and alike reactions, and many more) have been investigated for the treatment of emerging pollutants over the past 20 years (Klavarioti et al.,...Read more
Elimination of relevant pharmaceuticals in hospital wastewater from Colombia by combination of a biological system with a sonochemical process
(Corresponding) TORRES PALMA R., Serna-Galvis E., Silva-Agredo J.
Topic:
Advanced oxidation processes
This work presents the treatment of selected emerging concern pharmaceuticals in real hospital wastewater (HWW) from Tumaco-Colombia by combination of a biological system with a sonochemical process. Fifteen compounds, commonly present in HWW, were considered: acetaminophen, diclofenac,...Read more
Immobilized rGO/TiO2 photocatalyst for water purification
Zouzelka R., Brabec L., Remzova M., (Corresponding) Rathousky J.
Topic:
Advanced oxidation processes
The preparation of immobilized graphene–based photocatalyst layers is highly desired for environmental applications. In this study, the preparation of an immobilized reduced graphene oxide (rGO)/TiO2 composite by electrophoretic deposition (EPD) was optimized. It enabled quantitative deposition...Read more

Oxidation of waters containing caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720 W at pH=3.0 and T=25°C. The catalytic action of ferrous ion was studied in a range of [Fe]=0-100.0 mg/L and oxidant concentrations between [H2O2]=0-250.0 mM. The oxidation of...Read more
Oxidation of carbamazepine by photo-Fenton treatment
Lomas J., (Corresponding) Villota N., Ferreiro C., Lombraña J.
Topic:
Advanced oxidation processes
Oxidation of waters containing 50.0 mg L-1 of carbamazepine was conducted by a photo-Fenton reagent employing a UV lamp of 150W, at pH=3.0 and T=40°C. The oxidising action of hydrogen peroxide was studied in a range between [H2O2]0=0-15.0 mM. When applying stoichiometric ratios of 2 mol C15H12N2O:...Read more
Mitigation of Microcystis sp. with metallic peroxide granules: matrix effect on hydrogen peroxide release kinetics and toxicity study on invertebrates
Keliri E., Christofi M., Efstathiou N., (Corresponding) Antoniou M.
Topic:
Advanced oxidation processes
An array of mitigation strategies has been applied over the years for toxic blue-green algae with the most recent one to be hydrogen peroxide (H2O2). Hydrogen peroxide has been widely used as an alternative to copper algaecides, and it is perceived as a more environmentally friendly option for...Read more

Catalytic Enhancement of Ozone-Based Processes for Removal of Selected Antibiotics from Wastewaters
(Corresponding) Žgajnar Gotvajn A., Derco J., Antončič T., Vrabel M.
Topic:
Advanced oxidation processes
The aim of our work was to use advanced oxidation processes based on formation of reactive hydroxyl radicals (OH·) due to ozonation and its combination with H2O2, Fe2+ as catalyst and UV light for removal of Amoxicillin and Levofloxacin from model wastewaters at different pHs. Removal efficiencies...Read more
Investigation of variables affecting UV-LED photocatalytic degradation of antibiotics ciprofloxacin and sulfamethoxazole
(Corresponding) Bertagna Silva D., Buttiglieri G., Babić S.
Topic:
Advanced oxidation processes
In this study, photolytic and photocatalytic degradation of two antibiotics in ultra-pure water were analyzed. A lab-scale cylindrical reactor had its inner walls impregnated with TiO2 nanofilm for the photocatalytic experiments. In the first step, an optimized photoreactor design was chosen based...Read more
New pillared clays for the removal of pollutants from wastewater by treatment with oxidation processes
(Corresponding) Kalmakhanova M., Massalimova B., Diaz de Tuesta J., Gomes H.
Topic:
Advanced oxidation processes
The constant development of technological processes aggravates the problem of pollution, due to a significant change in the composition of effluents that makes necessary the development of new (and/or improvement of the existing) treatment methods and catalytic materials. In this sense, the use of...Read more
