SUMMARY:Webinar: PFAS monitoring
DESCRIPTION:The PFAS family comprises approximately 4700 different man-made compounds categorised into different sub-sets. The physiochemical properties of PFAS render them extremely resistant to degradation\, hence they are often referred to as “forever chemicals”\, due to their persistence in the environment. \nOn 8th June 2021 \, from 4 pm – 5 pm CEST\, Sensileau is organising a webinar about PFAS. PFAS in water are a serious problem and more and more we are becoming aware of the dangers. In this webinar\, we shall focus on monitoring and the removal of PFAS from (drinking) water. We are going to invite two speakers: \nNajmeh Karimian\, working at the Department of Molecular Sciences and Nanosystems at the university of Venice\, will tell us about the PFAS sensor they have developed.\nMany limitations within existing methods of PFAS determination\, such as high cost\, long analysis times\, and centralized instrumentation\, can be addressed through the development of PFAS-detecting sensors. Robust\, rapid\, sensitive\, inexpensive\, and reliable techniques to quantify PFAS in the field are necessary to diagnose environmental contamination at the earliest onset of pollution. The university of Venice created an electrochemical sensor to detect PFOS. The sensor has a low detection limit\, a satisfactory selectivity\, and is reproducible and repeatable\, giving analytical results in good agreement with those obtained by HPLC-MS/MS analyses. \nTali Harif\, CCO at Puraffinity\, will tell us about the removal of PFAS from water.\nPFAS removal from water is highly challenging due to their unique physiochemical properties\, derived from a high degree of fluorination and the extremely high strength of the carbon-fluorine (C-F) bond. In addition\, the diversity of the PFAS family\, new regulations that now include broad spectrum PFAS removal\, and the different treatment challenges posed depending on which PFAS compounds are being targeted\, highlights the need for a flexible design approach for broad spectrum PFAS water treatment.\nAdsorption is the preferred method for removing PFAS from water\, due to low energy requirements\, non-complex operations\, and installation ease. However\, PFAS selectivity and adsorption capacity are pivotal in ensuring adsorbent materials are able to (1) remove the target contaminant in water containing additional typical constituents\, which can interfere and/or compete with adsorption sites and (2) provide operational reliability and acceptable usage times until the adsorbent requires replenishing.\nTali will explain how Puraffinity has developed a technology platform that facilitates functionalisation of various substrates\, whilst focussing on development of highly PFAS selective unique materials\, possessing also a high adsorption capacity.
