  1. 6. Temperature-dependent waterbinding on potassiumbirnessite : A potential sorbent for atmospheric water harvesting

    University essay from Umeå universitet/Kemiska institutionen

    Author : Hanna Oderstad; [2022]
    Keywords : ;

    Abstract : The nanolayered manganese oxide birnessite (MnO2) is a naturally occurring mineralin soils and sediments. Its ability to capture and store water within its interlayers, andits great solar absorptivity, could be a part of the solution to global water shortage. READ MORE

  3. 7. Fluoride removal by low-cost adsorbents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Fredrik Bernheim; [2022]
    Keywords : Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Abstract : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. READ MORE

  4. 8. Simulation Testbed for Liquid Chromatography

    University essay from Umeå universitet/Institutionen för fysik

    Author : David Andersson; [2021]
    Keywords : ;

    Abstract : The stlc package is proposed as a tool for simulation of liquid chromatography by implementing several lumped kinetic models which combine diffusive mass  transport and adsorption isotherm equations. The purpose of the package is to provide computationally efficient approximations to the general rate model of chromatography. READ MORE

  5. 9. Modelling Competitive Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil and Sorbents

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Linnea Georgii; [2021]
    Keywords : PFAS; modelling; competitive sorption; adsorption; isotherms; PFAS; modellering; konkurrenseffekter; adsorption; isotermer;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) have become contaminants of increasing concern to society due to the contamination of drinking water and the ecosystem. A better understanding of the sorption and transport of PFASs in soil systems is urgently needed, however there have been few studies dedicated to investigating competitive sorption among PFASs, and there is no available model to model such effects.

  6. 10. Downscaling and modelling of an ion-exchange chromatography column for purifying glucose solutions

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Viktor Geraldsson; [2020]
    Keywords : Ion-exchange; chromatography; glucose; purification; modelling; equilibrium isotherm; Matlab; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Abstract : To utilize sugars as a feedstock for renewable industries, the feedstock often needs to be very pure. This is due to ionic species contaminating the sugar feedstock being potent catalyst poisons in many cases. To remove ionic species from the sugar feedstock, it is dissolved and purified using packed ion-exchange columns. READ MORE
