  1. 6. 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

  3. 7. Microgels as drug carriers : Relationship between release kinetics and self-aggregation of the amphiphilic drugs adiphenine, pavatrine and diphenhydramine.

    University essay from Uppsala universitet/Institutionen för läkemedelskemi

    Author : Lobna Ali Mohsen; [2021]
    Keywords : Amphiphilic drugs; small angle x-ray scattering; macrogels; binding isotherm; CMC; self-aggregation; phase structure; micelles.;

    Abstract : Abstract There has been great interest in microgels as drug carriers within the pharmaceutical industry. This includes the use of amphiphilic drugs for treating conditions such as depression, allergies, and cancer. READ MORE

  4. 8. 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.

  5. 9. Implementation of the mille-feuille nanofilter paper in the virus removal filtration of IgY purified from chicken egg yolk

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Michelle Dahlman; [2020]
    Keywords : ;

    Abstract : The purpose of this thesis was to test the mille-feuille nanofilter paper for a virus removal filtration from a potential protein-based nutraceutical. Therefore, chicken IgY was purified from egg yolk, with PEG precipitation for crude fractionation followed by thiophilic adsorption chromatography. READ MORE

  6. 10. Binding of per- and polyfluoroalkyl substances (PFASs) to organic soil horizons of peat and mor : effect of solution chemistry and soil organic matter composition

    University essay from SLU/Dept. of Soil and Environment

    Author : Jennifer Makselon; [2019]
    Keywords : sorption; electrostatic interactions; isotherms; partitioning coefficient; soil organic matter; cation; PFOS; PFOA; desorption;

    Abstract : The understanding of sorption processes of per- and polyfluoroalkyl substances (PFASs) in soils is important for the determination of their fate and transport in the environment. The sorption behavior of PFASs of varying chain length and hydrophilic headgroup was studied in three organic soils, two peat soils and one mor layer, with differing chemical composition of the soil organic matter (SOM).
