Perfluorinated Organic Compounds (PFCs) Degradation using Non-Thermal Plasma Enhanced by Boron Doped Graphene Oxide as Catalyst


Perfluorierte Verbindungen aus Trink- und Grundwasser entfernen

Perfluorierte Verbindungen sind eine Gruppe toxischer Chemikalien, die sich über längere Zeiträume hinweg in der Umwelt halten. Diese künstlichen Chemikalien wurden im Trink- und Grundwasser entdeckt, was ernste Bedenken in Bezug auf die menschliche Gesundheit aufwirft. Bislang konnten moderne Oxidationsverfahren, einschließlich Fenton-Reagenzien, Ozon, ultraviolettem Licht oder Katalysatoren, diese Chemikalien nur mit begrenztem Erfolg reduzieren und entfernen. Im Rahmen des EU-finanzierten Projekts PFCsByPlasCat wird eine alternative Behandlungsoption getestet, die als nicht thermische Plasmas, die mehrere reaktive Spezies gleichzeitig produzieren, bekannt ist. Es werden verschiedene Nanokatalysatoren getestet, darunter bordotiertes Graphenoxid, um die Effizienz des neuen Hybrid-Plasma-Katalysatorprozesses zu maximieren. Um den Prozess zu validieren, werden auch echte Proben mit kontaminiertem Grundwasser getestet.


The extensive use of perfluorinated compounds (PFCs) in many industrial/commercial applications, as surfactants, emulsifiers, etc., and their high chemical stability are responsible for their ubiquitous presence in the environment. Specifically, the contamination of groundwater and drinking water supplies by perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) is raising great concern as more data on PFCs toxicity in humans and wildlife is becoming available. Thus, a parallel surge in monitoring campaigns and in the search for innovative water treatment technologies for PFCs is required. Since PFCs are highly resistant to degradation by standard chemical and biological processes, advanced oxidation processes (AOPs) are being considered and, including Fenton, ozone and UV irradiation with catalysts, applied so far with limited success. Among innovative AOPs, air non-thermal plasmas (NTP), which produce several reactive species at a time, have been recently tested for the treatment of PFOA/PFOS yielding promising results. The proposed research aims to advance the state of art by developing an innovative treatment process for PFCs in which NTP is applied in combination with novel boron-doped graphene oxide (B-GO) nano photocatalysts. The catalysts synthesized and characterized by the Researcher will be tested on prepared solutions of PFOA and PFOS using various NTP reactors which are available in the beneficiary laboratory. The best catalyst-reactor combination will thus be identified; conditions and parameters will be optimized to maximize the synergy between plasma and catalyst and the efficiency of the novel hybrid plas-cat process. Real samples of contaminated groundwater will be tested to verify the process applicability to complex matrices. For excellence of research, basic guidelines will be drawn and disseminated for implementing an efficient hybrid plas-cat process in view of auspicable scaling-up and technology transfer to stakeholders.
