In this study, eight different Ti and Al based catalyst were employed for the investigation of photocatalytic PFOS degradation. The maximum PFOS concentration used was 50 ppm. The experiments were conducted at 20 °C in an open cylindrical polypropylene reactor, and a simulated solar radiation lamp (Solimed BH Quarzlampen) was used as a light source. Photocatalysis was monitored up to 8 hours. The range of degradation was 50-78%. Analysis of degradation products indicated that the dominant method of transformation is oxidation. Additionaly, ecotoxicity to Allivibrio fischeri of both PFOS and photocatalytic degradation products was assessed. The obtained results confirmed the possibility of remediation of PFOS and related compounds in aquatic environment.
