A Game-Changing Method: One-Step Strategy for Aqueous PFAS Remediation

PhD defence, 6 December 2023, Xingaoyuan Xiong

Xingaoyuan Xiong

During her PhD studies, Xingaoyuan Xiong delves into the complete destruction of trace-level PFAS in aquatic environments, famous for its persistence and detrimental impacts on both human health and the environments. Employing the intrinsic properties of PFAS, Xingaoyuan Xiong developed one-step method for PFAS accumulation-and-destruction, with a key focus on preventing of shorter-chain analogues formation and minimizing energy consumption. The underlying mechanism was thoroughly elucidated as well.

The outcomes of this research advance PFAS remediation strategies and contributes to the ultimate goal of achieving zero fluoro-pollution.


The PhD study was completed at Department of Biological and Chemical Engineering, Faculty of Technical Sciences, Aarhus University.
