  1. 1. Per- and Polyfluoroalkyl Substance (PFAS) Emissions from Recycling Processes of Lithium-Ion Batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Amanda Rensmo; [2022]
    Keywords : lithium-ion; battery; PFAS; recycling; LIB recycling; ion chromatography; hydrometallurgy; thermal processes; persistent;

    Abstract : The lithium-ion battery (LIB) recycling industry is currently under development to improve the yields for critical metals. However, the organic components of LIBs must also be handled, which may result in harmful chemical emissions as by-products. READ MORE

  3. 2. A Comparative Analysis of Per- andPolyfluoroalkyl Substances (PFAS) and ExtractableOrganofluorine (EOF) Using Solid PhaseExtraction-Weak Anion Exchange and Ion PairExtraction in SerumMarichal SalamehSpring 2021Independent project

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Marichal Salameh; [2021]
    Keywords : Extractable organofluorine EOF ; Per- and polyfluoroalkyl substances PFAS ; horse serum; human serum; ion pair extraction IPE ; solid phase extraction - weak anion exchange SPE-WAX ; liquid chromatography tandem mass spectrometry LC-MS MS ; combustion ion chromatography CIC ;

    Abstract : Per- and polyfluorinated substances (PFAS) are compounds that consist of a carbon chainbackbone that is partially or entirely fluorinated, with an addition of a functional group. SomePFAS are known as persistent organic pollutants (POPs) and have therefore been drawing a lot ofattention as well as increased concerns. READ MORE

  4. 3. 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.

  5. 4. 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
