  1. 11. Surface complexation in natural particle suspensions

    Författare :Qing Du; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : This thesis is a summary of our studies on (i) the proton and copper adsorption at aqueous illite surfaces, (ii) the proton and copper complexation of humic substances (fulvic acid FA and humic acid HA), (iii) the interaction between illite and fulvic acid, and (iv) the copper complexation behaviors in illite-FA bi-complexant systems. These particular studies were designed to help us develop a framework for modelling heavy metal complexation/adsorption mechanisms at natural particle surfaces. LÄS MER

  3. 12. Measurement and Modelling using Surface Complexation of Cation (II to VI) Sorption onto Mineral Oxides

    Författare :Anna-Maria Jakobsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surface complexation; goethite; UO2.sup.2 ; alumina; sorption; Co.sup.2 ; NpO2.sup. ; Pm.sup.3 ; Th.sup.4 ; TiO2;

    Sammanfattning : The aim of this work was to experimentally and theoretically study some surface complexation models and how well these can be applied to a simple system. This is done while keeping in mind the interest in including some type of chemical model in performance assessment calculations for much more complex systems. LÄS MER

  4. 13. Sorption and Surface Complexation of Plutonium

    Författare :Mattias Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plutonium is a constituent of spent nuclear fuel. As such, its behavior in contact with the surfaces of solids is of interest. This behavior will affect the migration of plutonium in case it is released into the environment. The chemistry of plutonium is rather complex. LÄS MER

  5. 14. Interpolymer complexation of a polymer brush

    Författare :John Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional materials; macromolecular gating; Interpolymer complex; nanopores; polymer brush; pH responsive;

    Sammanfattning : Controllable macromolecular gating between nanoscopic compartments is of high interest for single molecule studies of biological macromolecules. By definition, a good macromolecular gate should completely stop biomolecules, such as proteins, from crossing between compartments in its closed state while letting them pass in its open state.
