  2. 1. Chlorite: Geochemical properties, Dissolution kinetcis and Ni(II) sorption

    Author : Åsa Zazzi; Zoltan Szabo; Susanna Wold; Peter Vilks; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chlorite; dissolution kinetics; Ni II sorption; surface complexation; Chemistry; Kemi;

    Abstract : In Sweden, among other countries, a deep multi-barrier geological repository, KBS-3, is planned for the burial of nuclear waste. One of the barriers is identified as the grantic bedrock itself and in this environment chlorite is present at surfaces in fracture zones. READ MORE

  5. 3. Sorption and weathering properties of naturally occurring chlorites

    Author : Åsa Gustafsson; KTH; []
    Keywords : chlorite; nickel; sorption; surface complexation; dissolution rate.;

    Abstract : Chlorite is a ferrous silicate mineral occurring as afracture filling mineral in the Swedish granite bedrock thatsurrounds the area of the candidate Swedish geologicalrepositories for nuclear waste. To investigate the importance of chlorites as a naturalbarrier for radionuclide migration sorption of Ni(II) onto anatural chlorite was chosen as the studied system. READ MORE

  6. 4. Oxygen-dependent regulation of key components in microbial chlorate respiration

    Author : Miriam Hellberg Lindqvist; Thomas Nilsson; Stefan Nordlund; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic respiration; Gene expression; Chlorate; Chlorate reductase; Chlorite dismutase; Kemi; Chemistry;

    Abstract : Contamination of perchlorate and chlorate in nature is primarily the result of various industrial processes. The microbial respiration of these oxyanions of chlorine plays a major role in reducing the society’s impact on the environment. READ MORE

  7. 5. Enzymes and electron transport in microbial chlorate respiration

    Author : Jan Bohlin; Thomas Nilsson; Lars-Gunnar Franzén; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ideonella dechloratans; c cytochromes; chlorate; chlorate reductase; chlorite dismutase; heterologous expression; heme reconstitution; electron transport; oxidoreductas; Chemistry; Kemi; Kemi; Chemistry;

    Abstract : Microbial chlorate respiration plays an important role in the turnover of oxochlorates in nature and industrial waste management. This thesis deals with the characterization of the molecular components of chlorate respiration in Ideonella dechloratans. READ MORE
