1. Solubility and Surface Complexation Studies of Apatites
Abstract : Apatites are a diverse class of phosphate minerals that are important in a great variety of natural and industrial processes. They are, for example, used as raw material in fertiliser production and in the remediation of metal-contaminated soils. READ MORE

2. Surface Complexation Studies in An (Th, U(IV), Pu(VI)) Systems
Abstract : Two-phase systems containing an electrolyte solution and a suspended solid were studied. The common denominator for the three systems examined in this work is that they contain actinides (elements of atomic numbers between 89 and 103) in either the solid phase or as a sorbate. Experiments were done on simple oxides. READ MORE

3. Measurement and Modelling using Surface Complexation of Cation (II to VI) Sorption onto Mineral Oxides
Abstract : 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. READ MORE

4. Surface complexation in natural particle suspensions
Abstract : 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. READ MORE

5. Sorption and Surface Complexation of Plutonium
Abstract : 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. READ MORE
