  3. 27. Assessment of vanadium sorption by different soils.

    University essay from KTH/Mark- och vattenteknik

    Author : Golshid Hadialhejazi; [2012]
    Keywords : Vanadium; soil; Freundlich model; sorption;

    Abstract : Vanadium is a white bright metal that belongs to group 5 in the periodic table of elements. It can exist in different oxidation states from -2 to +5 although the forms can be found naturally in the environment are (III), (IV) and (V). As vanadium is toxic at high concentrations, and as vanadium is a common contaminant from e.g. READ MORE
