  1. 1. Faradaic Reactions in Capacitive Deionization : A Comparison of Desalination Performance in Flow-through Cell Architectures

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : John Bradley; Miranda Carlström; [2023]
    Keywords : Capacitive deionization; Faradaic reactions; Flow-through CDI; Upstream anode; Downstream anode; Desalination Performance; pH fluctuations;

    Abstract : Capacitive Deionization (CDI) is an energy-efficient desalination technology that utilizes an electric field to extract ions from water. Flow-through CDI systems show potential for superior desalination performance compared to traditional flow-by CDI; however, they face the challenge of increased occurrence of Faradaic reactions, leading to undesired by-products and reduced energy efficiency.

  3. 2. Application of electrodes with redox mechanisms for the desalination of water

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Pablo Moreno Cerezo; [2023]
    Keywords : Activated Carbon Cloth ACC ; Capacitive Deionization CDI ; Cyclic Voltammetry CV ; Electrochemistry; Polyaniline PANI ; Prussian Blue PB and Redox Reactions; Aktivt koltyg ACC ; Kapacitiv avjonisering CDI ; Cyklisk voltammetri CV ; Elektrokemi; Polyanilin PANI ; Preussisk blå PB och Redoxreaktioner;

    Abstract : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. READ MORE

  4. 3. Modeling competitive adsorption of binary mixtures of volatile organic compounds

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

    Author : Michelle Janus; [2023]
    Keywords : ;

    Abstract : Adsorption is a common technique for the removal of volatile organic compounds (VOCs) from industrial waste streams. The multi-component adsorption on zeolites, particularly the interactions between VOCs and water vapor is sparsely understood and is yet to be described by empiric and full-physical models.

  5. 4. How is carbon stored in boreal forest soils? - A method development which investigates at what protein concentration ferrihydrite and goethite are saturated.

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Louise Berild; [2023]
    Keywords : Soil nitrogen; soil carbon; boreal forest; ectomycorrhizal fungi; decomposition; adsorption; ferrihydrite; goethite; Earth and Environmental Sciences;

    Abstract : Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. READ MORE

  6. 5. Investigating the Adsorption of Per- and Polyfluoroalkyl Substances on Amine-functionalized Mesoporous Carbons

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : MOJISOLA SALISU; [2023]
    Keywords : Mesoporous carbon; PFOA; PFOS; PFAS; Rose Bengal; Adsorption;

    Abstract : Water pollution is a profound ecological concern, exerting detrimental effects on human well-being, ecological systems, and animal life. Among the emerging contaminants that critically influence water quality and have garnered substantial scientific interest in recent times are per- and polyfluoroalkyl substances (PFAS). READ MORE
