  1. 11. Sorption of per- and polyfluoroalkyl substances (PFAS) in contaminated water using sustainable organic- and inorganic materials

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Natalie Storm; [2022]
    Keywords : Sorption | PFAS | Contaminated water | Bark | Steel slag | Biochar | Activated carbon;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) are a large group of anthropogenic compounds with unique properties, including chemical inertness, resistance to many degradation processes and amphiphilic structure. This makes them useful in a range of applications, but also very persistent and bioaccumulative in nature, where PFAS have been linked to adverse health effects in both animals and humans. READ MORE

  3. 12. Experimental characterization of a specific chemisorbent and a physisorbent for direct air capture application : Analyzing the effect of parameters such as desorption temperature, humidity and varying CO2 partial pressure on the performance of the adsorbent material. (Thesis work carried out at The Netherlands Organization for Applied Scientific Research (TNO), Delft, The Netherlands)

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : MIT RAKESH SURATI; [2022]
    Keywords : ;

    Abstract : Climate change has become an indisputable threat to the planet with global warming being at the forefront. With continuous usage and combustion of fossil fuels, the atmospheric CO2 concentration has kept on increasing leading to higher average temperatures globally. READ MORE

  4. 13. Designing Mesoporous Test Sticks for Measuring PFAS Concentrations in Water

    University essay from Linköpings universitet/Nanostrukturerade material

    Author : Amanda Hillås; [2022]
    Keywords : Mesoporous material; PFAS; PFOA; PFOS; Rose Bengal; adsorption;

    Abstract : Water contamination through substances called per- and polyfluoroalkyl substances (PFAS) is a worldwide problem. Being able to measure the concentrations of PFAS in water is a first step towards beating this contamination. One alternative is to use a field test kit instead of extensive lab equipment to monitor the contaminated areas. READ MORE

  5. 14. Purification of watercontaminated by poly- andperfluorinated chemicals : Analysing the efficiency of the combinedtechniques ion exchange resin and rotating bedreactor

    University essay from Umeå universitet/Kemiska institutionen

    Author : Jessica Borgström Mellergård; [2021]
    Keywords : ;

    Abstract : Development and usage of poly-and perflourinated chemicals has increased considerablysince their discovery. They have since then polluted our environment and are exposed tohumans via drinking water and sea food amongst others. READ MORE

  6. 15. Magnetic Activated Carbon Production from Lignin and Ferrous Salts : Process Modification for Enhanced Phosphate Adsorption from Aqueous Solutions

    University essay from KTH/Materialvetenskap

    Author : Zhaoran Zheng; [2020]
    Keywords : Magnetic bio-activated carbon; phosphate adsorption; lignin; steam activation.; Magnetiskt bioaktiverat kol; fosfatadsorption; lignin; ångaktivering;

    Abstract : The treatment and control of superfluous aqueous phosphate is a critical task in environmental management. Magnetic bio-activated carbon is a good adsorbent for physical adsorption methods with several environmental and economic advantages. READ MORE
