Our research is focused on harnessing the solar photocatalytic capabilities of titanium dioxide (TiO2) and a novel phosphotungstic acid (PW12) - titanium dioxide complex catalyst for the degradation of PFAS compounds present in wastewater. To mimic real-world scenarios, heptafluorobutyric acid (HFBA) is employed as a model pollutant, and its removal is assessed using both commercially available TiO2 and in-situ synthesized PW12-TiO2 catalysts in conjunction with a solar simulator. The outcomes are quantified via UV-Vis Spectrophotometry and fluoride ion selective electrode analysis, adhering to the EPA Test Method 9214 for monitoring fluoride ion in aqueous samples.
