Combination of electrochemistry with sono to destroy and detoxify PFAS

以前处理全氟烷基和多氟烷基物质的主要方法是通过吸附，从污染场地收集和去除全氟烷基物质。然而，PFAS仍然存在，未降解，等待销毁。针对目前的修复/吸附工厂的泥浆废物，该项目旨在通过将电化学氧化与声化学相结合来有效降解PFAS，以提高降解能力，加速PFAS从泥浆废物中的解吸/运输，避免电极结垢并使PFAS解毒。该项目的预期成果是清理受污染的场地，包括全氟辛烷磺酸/前体和其他持久性有机污染物，从而产生重大的环境效益。

Previously the major means of dealing with per- and poly-fluoroalkyl substances (PFAS) is by adsorption, to collect and remove PFAS from contaminated sites. However, PFAS still exist, non-degraded and waiting for destruction. Targeting slurry waste from current remediation / adsorption plants, this project aims to efficiently degrade PFAS by combining electrochemical oxidation with sono-chemistry to enhance degradation capacity, to accelerate PFAS desorption / transportation from slurry waste, to avoid electrode fouling and to detoxify PFAS. The expected outcome of this project is to clean up contaminated sites, including PFAS / precursors and other persistent organic pollutants, leading to significant environmental benefits.
