Experimental data: a batch-flow photocatalytic LED system for diclofenac photodegradation

Data obtained for publication J. Wat. Proc. Eng. 62, 2024, 105397Authors and AffiliationsAdam Kubiak and Michał Cegłowski from the Faculty of Chemistry at Adam Mickiewicz University, Poznań, Poland.Data Collection DatesTests under real-world conditions at an operational sewage treatment plant were conducted in February 2024.Methodology and ToolsThe study involved fabricating a titanium dioxide (TiO2​) loaded carbon fiber photocatalyst using a hydrothermal process. The material's properties were analyzed using a comprehensive suite of methods including XRD, SEM, TEM, XPS, and Raman spectroscopy. The experiment was centered around a novel batch-flow photocatalytic system equipped with a custom LED light source (emitting at 365, 380, 390, and 410 nm). The entire setup, including the photoreactor and a recirculation pump, was sustainably powered by a 200W photovoltaic panel and a 26 Ah AGM gel battery. Diclofenac concentrations were quantified using an HPLC system, while its degradation byproducts were identified with ESI-MS analysis.Funding InformationThis work was funded by the National Science Centre of Poland, project number 2021/43/D/ST5/01190.
