  1. 1. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Niklas Gunnarsson; [2019]
    Nyckelord :Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Sammanfattning : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. LÄS MER

    Nyckelord :Kinnekulle; Kinne-Kleva; arsenic; black shale; rödfyr; carbonates; leaching; adsorption; Kinnekulle; Kinne-Kleva; arsenik; alunskiffer; rödfyr; karbonater; lakning; adsorption;

    Sammanfattning : For Sweden to achieve the environmental goal of a nontoxic environment, knowledge is required about harmful elements’ movement and mobility in nature. One of those elements is arsenic that for a long time has been known to cause health ailments. The most common and dangerous path into the human body is through drinking water. LÄS MER
