  1. 1. Thermal degradation of PFAS in solid matter

    University essay from KTH/Kemi

    Author : Tuqa Al-Badri; [2024]
    Keywords : PFAS; PFOS; PFOA; thermal degradation; sewage sludge; PFAS; PFOS; PFOA; termisk nedbrytning; avloppsslam;

    Abstract : Per- och Polyfluorerade alkylsubstanser (PFAS) är syntetiskt framställda organiska föreningar som har använts i stor utsträckning i konsument- och industriprodukter. PFAS-substanser besitter attraktiva egenskaper såsom resistans mot väta, fett, fläckar och är dessutom värmetåliga. READ MORE

  3. 2. Utility of bark chips for removal of fluorinatedorganic compounds in water samples at a hazardouswaste management facility

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Maria Ekesbo; [2021]
    Keywords : Pine bark; PFAS; extractable organofluorine; contaminated water and sorption efficiency.;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) are synthetic compounds that have beenaround since 1940. They can be used in a variety of products such as fire-fighting foam,food packaging and cosmetic products. Many PFAS have potential toxic effects on bothhumans and animals which poses a problem due to their wide distribution and persistency. READ MORE

  6. 5. A study to understand the information gap between total organofluorine analysis and total oxidizable precursor assay on polyfluoroalkyl/perfluoroalkyl substances (PFASs)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Pontus Larsson; [2018]
    Keywords : ;

    Abstract : Total oxidizable precursor (TOP) assay is an oxidation method to convert precursor compound of polyfluoroalkyl/perfluoroalkyl substances (PFASs) into measurable perfluorinated carboxylic acids (PFCAs). A previous mass balance study has shown that a loss of fluorine was observed after employing the method to convert the precursors in firefighting foams. READ MORE
