  2. 21. The Sink-Effect in Indoor Materials : Mathematical Modelling and Experimental Studies

    Author : Peter Hansson; KTH; []
    Keywords : sink-effect; sorption; adsorption; diffusion; indoor air quality; volatile organic compounds; VOC; contaminants; building materials;

    Abstract : In this thesis the sink-effect in indoor materials wasstudied using mathematical modelling and experimental studies.The sink-effect is a concept which is commonly used tocharacterise the ability of different indoor materials to sorbcontaminants present in the indoor air. The sorption process ismore or less reversible, i.e. READ MORE

  4. 22. Surface Complexation Studies in An (Th, U(IV), Pu(VI)) Systems

    Author : Mattias Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; surface complexation; sorption; adsorption; uranium; surface charge; FITEQL; plutonium;

    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

  5. 23. Bioavailability of organic contaminants in a changing climate

    Author : Matyas Ripszam; Peter Haglund; Roland Kallenborn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; organic contaminants; sorption; dissolved organic carbon; bioavailability;

    Abstract : The effects of predicted future climate change was investigated with special emphasis on the association of organic contaminants with dissolved organic carbon (DOC) in the Baltic Sea.An automated method was developed for the measurements of DOC - water distribution constants at realistic DOC concentrations in brackish water.

  6. 24. On diffusion of organic colloids in compacted bentonite

    Author : Susanna Wold; KTH; []
    Keywords : Diffusion; sorption; Humic Substances; Bentonite;

    Abstract : 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. READ MORE

  7. 25. Limitations and possibilities for microbial degradation of organic contaminants in aquifers

    Author : Christel Carlsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ekologi; mycology; Mikrobiologi; Hydrobiology; biodegradation; Organic contaminants; redox conditions; sorption; DOM; cometabolism; biomass; microbial activity; microbial community composition; Ecology; Microbiology; bacteriology; virology; bakteriologi; mykologi; virologi; aquatic ecology; marine biology; limnology; Miljökemi; Environmental chemistry; akvatisk ekologi; Marinbiologi; limnologi;

    Abstract : Many factors can influence the rate of microbial degradation of organic contaminants in aquifers. Some of these factors, e.g. READ MORE
