  1. 1. Ion pair chromatography of carboxylic and sulfonic acids with trialkylamines : An investigation of the relationship between the adsorption isotherm of the IPR and the retention factor of the analyte

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Karl Kullberg; [2023]
    Keywords : ;

    Abstract : Ion pair chromatography has found many uses within analytical chemistry and understanding of the chromatographic process with an ion-pairing reagent have been studied since the 1970s. The adsorption of the Ion-pairing reagent to the stationary phase is understood to be important and many studies have been dedicated to looking at the adsorption isotherms of the earlier quaternary alkylammonium ions.

  3. 2. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : William Gulding; [2023]
    Keywords : Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Abstract : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. READ MORE

  4. 3. 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

  5. 4. Techno-economic Assessment of Carbon Capture from Low Concentration Streams

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

    Author : Prithvi Kiran Joshi; [2023]
    Keywords : Carbon capture; industrial emissions; low concentration; MEA; Benfield; absorption; Immobilised Amine; adsorption; Kolavskiljning; industriella utsläpp; låg koncentration; MEA; Benfield; Absorption; Immobiliserad amin; Adsorption vi;

    Abstract : Investments in carbon capture from industrial emissions have been on the rise in recent years, having reached over $200 million in 2021 as compared to 2015’s $13 million. The Paris Agreement, signed by 196 parties globally in 2015, is purported to be the primary driver for this, with its ambitious goal of limiting global surface temperature rise to 1. READ MORE

  6. 5. A Quantum Chemical Investigation of Chemical Vapour Deposition of Fe using Ferrocene and Plasma Electrons

    University essay from Linköpings universitet/Kemi

    Author : Felicia Andersson; [2023]
    Keywords : Quantum chemistry; Ferrocene; Silver; Ag 111 ; Plasma electrons; Surface chemistry; Electronic structure; DFT; Kvantkemi; Ferrocen; Silver; Ag 111 ; Plasmaelektroner; Ytkemi; Elektronstruktur; DFT;

    Abstract : Thin films provide a remarkable asset, as depositing a thin surface layer can completely alter a material’s characteristics and provide new, inexpensive, and valuable properties. In 2020, a new Chemical Vapour Deposition (CVD) approach was developed at Linköping University, using plasma electrons as reducing agents for the deposition of metallic thin films. READ MORE
