Complete Reductive Defluorination of PFAS by Hydrated Electrons Generated from 3-Indole-acetic-acid in Chitosan-Modified Montmorillonite
Abstract
Perfluorinated compounds (PFCs) are extensively utilized industrial compounds with a wide variety of applications (Sznajder-Katarzyska et al., 2019). They find heavy use due to their hydrophobic alkyl chains which are attached to hydrophilic end groups. These compounds are useful in various industrial applications such as textiles (Supreeyasunthorn et al., 2016), carpet manufacturing (Lau et al., 2007), food packaging (Begley et al., 2005), and leathertreatment (Sznajder-Katarzyska et al., 2019). They are also used as surfactants and fire-fighting foam (Houtz et al., 2013). These compounds have found such prolific use because of the strength of the carbon - fluorine bond, which requires 485 kJmol-1 to break (O'Hagan, 2008), making PFCs long lasting as they are thermally stable and resistant to oxidation. Because of their widespread applications, PFCs have made into the EPAs list of emerging contaminants as they are persistent, bio-accumulative, and have been shown to be both environmentally hazardous and potentially carcinogenic (Cooke, 2017; SznajderKatarzyska et al., 2019).
