  2. 6. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites

    Author : Ylva Persson; Mats Tysklind; Lars Öberg; Staffan Lundstedt; Jaana Koistinen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; contaminated soil; hydrophobic organic contaminant; chlorinated phenoxyphenol; chlorinated diphenyl ether; chlorinated dibenzofuran; chlorinated dibenzo-p-dioxin; preservation; mobility; colloid; dissolved organic matter; particulate organic matter; groundwater; equilibrium column test; chlorophenol; Environmental chemistry; Miljökemi;

    Abstract : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. READ MORE

  5. 8. The Influence of Polyelectrolytes on the Stability of Colloids

    Author : Lena Sjöström; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electrostatic interaction; charge reversal; colloid; asymmetric systems; electric double layer; polyelectrolyte; Monte Carlo; Physical chemistry; Fysikalisk kemi;

    Abstract : The interaction between two colloids with grafted polyelectrolytes in aqueous solution is studied within the primitive model by Monte Carlo simulations. For neutral colloids with grafted polyelectrolytes and in absence of salt the interaction is strongly repulsive in absence of salt. READ MORE

  6. 9. Theoretical and Experimental Studies of Polymer Adsorption and Polymer Mediated Interactions

    Author : Fei Xie; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte; Adsorption; Colloid; Polymer; Dispersion; Interation; Ellipsometry; Monte Carlo Simulation; Classical Density Functional Theory;

    Abstract : Polyelectrolyte adsorption and polymer mediated interactions in different colloidal polymer systems have been studied in this work. Theoretical methods and experimental techniques are combined, in order to obtain more general reliable results, as well as a deep understanding of the molecular mechanisms that are responsible for the observed behaviors.

  7. 10. The bentonite barrier : microstructural aspects on colloid filtration and radiation effects on bentonite colloid stability

    Author : Michael Holmboe; Mats Jonsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry;

    Abstract : In many countries a multi-barrier concept in a deep geological repository is planned for final disposal of nuclear waste. Many of these different concepts, for example the Swedish KBS-3 model, include an engineered barrier consisting of compacted bentonite. READ MORE
