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

TiO2/Fe2O3 based Composites for Solar-driven Photocatalytic Degradation of Amoxicillin

(Corresponding) dela Rosa F., Papac J., Kovačić M., (Corresponding) Kušić H., Božic A.

Topic:

Advanced oxidation processes

The occurrence of trace amounts of antibiotics in various bodies of water was directly linked to the development of antibiotic resistant pathogens. Recently, Amoxicillin (AMX) was added on the second EU “watch list” based on the proposed European Decision 2018/840/EU. Its presence in drinking water...Read more

Ηexavalent chromium reduction in a photocatalytic membrane reactor in the presence of organic acids

(Corresponding) Sarasidis V., Kyriakou E., Plakas K., Karabelas A.

Topic:

Advanced oxidation processes

This study deals with the photocatalytic reduction of carcinogenic hexavalent chromium, encountered in industrial effluents and surface waters, to much less toxic and harmful trivalent form. Experiments were performed in a pilot scale Photocatalytic Membrane Reactor employing titanium dioxide...Read more

Solar photocatalytic degradation of pharmaceutical compounds using ZnSnO3/CB composites

Kouvelis k., Petala A., (Corresponding) Frontistis Z., Kondarides D.

Topic:

Advanced oxidation processes

In this study, the activity of ZnSnO3 as a photocatalyst for the degradation of persistent micro–pollutants under simulated solar irradiation has been assessed. Zinc stannate (ZnSnO3), belongs to the class of ternary oxides and has a reported band gap of 2.4 eV. Due to its narrow band gap can be...Read more

Can mixed oxides act as efficient photocatalysts for the elimination of organic water pollutants?

(Corresponding) Favier L., Sescu A., (Corresponding) HARJA M., Siamer S., Lutic D.

Topic:

Advanced oxidation processes

New mixed-metal oxides containing zinc and lanthanum were prepared by coprecipitation. The synthesized nanocomposites were calcined, and characterized by scanning electron microscopy (SEM), X-ray diffraction, FT-IR, BET and DR analysis. The calcined sample showed a higher crystalinity, confirmed by...Read more
