1. 1. 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

3. 2. Evaluation of Dissolved Air Flotation for Water Purification: With Focus on Floc Characteristics and PFAS

   University essay from KTH/Kemiteknik

   Author : Ludwig Löf; [2021]
   Keywords : Water treatment; Sedimentation; Flotation; PFAS; Zeta potential; Vattenbehandling; Sedimentering; Flotation; PFAS; Zeta potential;

   Abstract : I detta projekt har experiment utförts med mål att förse kommunalförbundet Norrvatten med data som kan användas som underlag för beslutsfattande angående om deras fällningslinjer i vattenreningsprocessen ska köras i flotation eller sedimentering. För detta ändamål har koncentrationen av poly- och perfluorerade alkylsubstanser (PFAS) samt karaktär av agglomererade partiklar (flockar) undersökts och jämförts mellan fällningslinjer som körs i olika konfigurationer.

5. 4. Total oxidizable precursor assay: Applications and limitations. A study on the occurrence of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in Chinese Wastewater Treatment Plants

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Pontus Larsson; [2020]
   Keywords : ;

   Abstract : Total oxidizable precursor (TOP) assay is an in-lab method which oxidatively converts precursor compounds of poly- and perfluoroalkyl substances (PFASs) into measurable perfluorinated alkyl acids (PFAAs). The method is a very strong tool to semi-quantify PFASs that would otherwise be missed in conventional targeted analysis using liquid chromatography - tandem mass spectrometry (LC-MS/MS). READ MORE

6. 5. The study of organofluorine analysis applied to totaloxidizable precursor (TOP) assay to understand perandpolyfluoroalkyl substances (PFASs)

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Crystal Ho; [2018]
   Keywords : Poly- per-fluoroalkyl substances; total oxidizable precursor TOP assay; AFFFs; combustion ion chromatography; oxidation;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) are synthetic chemicals which are used in a wide range of applications such as aqueous film forming foam (AFFF) for firefighting, paint, coating and cosmetics. For almost a decade, PFASs have received worldwide attention because of the ubiquitous detection of PFAS in the environment and their bioaccumulative, persistent and give toxic effects on animals and humans.
