  1. 1. On diffusion of organic colloids in compacted bentonite

    Författare :Susanna Wold; KTH; []
    Nyckelord :Diffusion; sorption; Humic Substances; Bentonite;

    Sammanfattning : The main issue of this thesis was to obtain information ondiffusion and sorption behaviour on organic colloids incompacted bentonite through experimental studies. It was tostudy if bentonite is an efficient barrier for organic colloidsor not. LÄS MER

  4. 3. Environmental and health aspects of corrosion– importance of chemical speciation

    Författare :Yolanda Hedberg; Inger Odnevall Wallinder; Anna Karin Borg Karlsson; Susanna Wold; KTH; []
    Nyckelord :;

    Sammanfattning : During the last decades, the interest in corrosion of metals and alloys from an environmental and health perspective has increased rapidly as a consequence of stricter environmental and human exposure legislations, their extensive use as implant materials and an increasing understanding related to occupational and/or daily exposure to airborne particles. Corrosion-induced metal release, however, needs to be understood in detail and to include knowledge related to chemical speciation, i. LÄS MER

  5. 4. Stability and sorption capacity of montmorillonite colloids : Investigation of size fractional differences and effects of γ-irradiation

    Författare :Karin Norrfors; Susanna Wold; Daniel Kaplan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; montmorillonite; colloids; size effect; γ-irradiation; sorption; colloid stability; radionuclides; montmorillonit; kolloider; storlekseffekt; γ-bestrålning; sorption; kollodial stabilitet; radionuklider; Kemi; Chemistry;

    Sammanfattning : Bentonite clay is intended to form one of the barriers in most repositories of spent nuclear fuel located in granite. One important function of the bentonite barrier is to retard transport of radionuclides in the event of waste canister failure. Bentonite has a high sorption capacity of cations and its main constituent is montmorillonite. LÄS MER

  7. 5. Radiation Induced Processes at Solid-Liquid Interfaces

    Författare :Miao Yang; Mats Jonsson; Susanna Wold; Simon Pimblott; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the thesis, the reactions between water radiolysis products—H2O2, HO• and O2—with metals and metal oxides utilized in nuclear industry are studied. The reactions include not only surface reactions, e.g. redox reactions and catalytic decomposition of H2O2, but also solution reactions (Haber-Weiss reactions). LÄS MER
