전기분해를 이용한 PFCs 분해

In this study, electrolysis was used to decompose PFOS, PFOA, and PFBS in PFCs. Experiments were conducted under the conditions of voltage, electrolyte concentration, and individual or composite PFCs using STS and Ti electrode plates (interval 2 cm) in a batch type reactor (200 ml). PFCs were analyzed using LC/MS/MS (Thermo Scientific). The decomposition of PFOS, PFOA, and PFBS using electrolysis was confirmed to be 97.2%, 65.2%, and 50.6%. The higher the input energy or the higher the electrolyte concentration, the higher the decomposition ratio. It was confirmed that the decomposition ratio of the STS electrode plate was about 30% (PFOS) higher than that of the Ti electrode plate. Because of the SO3 - functional group and the -COOH functional group present in the sample, it was confirmed that PFOS → PFOA → PFBS had a great influence on the decomposition efficiency. That is, long-chain substances with high bioaccumulation properties were decomposed into short chains through electrolysis.
