  1. 1. Enzymes and electron transport in microbial chlorate respiration

    Author : Jan Bohlin; Thomas Nilsson; Lars-Gunnar Franzén; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

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

    Author : Miriam Hellberg Lindqvist; Thomas Nilsson; Stefan Nordlund; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  3. 3. Critical potential and oxygen evolution of the chlorate anode

    Author : Linda Nylén; Göran Lindbergh; Yohannes Kiros; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; chlorate; chloride oxidation; oxygen evolution; critical anode potential; chromate; DSA; mass transport; RDE; Chemical engineering; Kemiteknik;

    Abstract : In the chlorate process, natural convection arises thanks to the hydrogen evolving cathode. This increases the mass transport of the different species in the chlorate electrolyte. There is a strong connection between mass transport and the kinetics of the electrode reactions. READ MORE

  4. 4. Activated Cathodes for the Hydrogen Evolution Reaction in Chlorate Manufacture

    Author : Ann Cornell; Daniel Simonssom; KTH; []
    Keywords : chlorate; cathode; ruthenium dioxide; chromate;

    Abstract : .... READ MORE

  5. 5. Mathematical modelling and experimental simulation of chlorate and chlor-alkali cells

    Author : Philip Byrne; KTH; []
    Keywords : chlorate; chlor-alkali; current density distribution; current distribution; potential distribution; hydrodynamic behaviour; electrolysis; bubble-evolution;

    Abstract : The production of chlorate, chlorine and sodium hydroxiderelies heavily on electrical energy, so that savings in thisarea are always a pertinent issue. This can be brought aboutthrough increased mass transfer of reacting species to therespective electrodes, and through increased catalytic activityand uniformity of current density distribution at theseelectrodes.
