  1. 1. Remediation of per- and polyfluoroalkyl substances (PFAS) in contaminated water by sorption to pine- and spruce bark

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Rebecka Ayranci Dahlberg; [2023]
    Keywords : Per- and polyfluoroalkyl substances; sorption; pine bark; spruce bark; ultra-short-chain PFAS; short-and long-chain PFAS; elemental analysis; field-test;

    Abstract : PFAS are anthropogenic substances used in many different industrial operations and products because of their unique properties. Due to their negative impact on human health and environmental bioaccumulative characteristics different authorities have addressed the issue. In Sweden the limit is4 ng/L for four different PFAS in drinking water. READ MORE

  3. 2. Desulphurisation of cement flue gases

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ellen Sjöstrand; [2023]
    Keywords : Flue Gas Desulphurisation; FGD; gypsum; cement;

    Abstract : Flue gas desulphurisation (FGD) is a crucial method to minimise the SO2 emissions from industrial processes. The FGD system utilise an alkaline sorbent to remove SO2 from the flue gases. Calcium in form of limestone is a commonly used sorbent where gypsum is produced asa by-product. READ MORE

  4. 3. Do selected CF3-containing pharmaceuticals oxidize to trifluoroacetic acid (TFA)? – Analysis of ultra-short perfluoroalkyl acids (PFAAs) and their analytical challenges following oxidation

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Johanna Gillberg; [2022]
    Keywords : ;

    Abstract : Total oxidizable precursor assay (TOPA) has been used to understand the contribution of unknown precursors to the extractable organofluorine (EOF) compounds. The investigation of compounds containing a CF3 moiety especially connected to an aromatic ring is important because any compounds with such a moiety (pharmaceuticals) may oxidize to form trifluoroacetic acid (TFA).

  5. 4. REMOVAL OF PFAS FROM WASTEWATER THROUGH ADSORPTION AND SORBENT INCINERATION

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Aston Sandblad; [2022]
    Keywords : PFAS; Adsorption; Incineration;

    Abstract : Per- and polyfluoroalkyl substances, PFAS, are a manufactured group of chemicals that have been found to be toxic to humans and the environment. Exposure to PFAS may include birth defects for infants as well as an increased risk of cancer. READ MORE

  6. 5. 3D Printing of Magnesium- and Manganese-Based Metal-Organic Frameworks for Gas Separation Applications

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Dhruva Deole; [2022]
    Keywords : 3D Printing; Additive Manufacturing; Metal-Organic Frameworks; Carbon Capture; Gas Separation;

    Abstract : Metal Organic Frameworks (MOFs) are a class of porous materials that are predominantly obtained as powders and have been investigated as a solid sorbent for gas separation or carbon capture applications from combustion exhaust gases. The manufacturing of products with MOFs to use them for real life applications is still a major problem. READ MORE
