  1. 1. Titanium(IV) Phosphates : The Next Generation of Wastewater Sorbents

    Författare :Mylene Trublet; Oleg Antzutkin; Anna-Carin Larsson; Marina Maslova; Nigel Clayden; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Treatment of industrial waters containing heavy metal ions is essential before being discharged into the environment. Consequently, European regulations have been established to control and limit the amount of heavy metals released. LÄS MER

  3. 2. Interaction of magnetite with soluble silicates and bentonite : implications for wet agglomeration of magnetite concentrate

    Författare :Xiaofang Yang; James McQuillan; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; Fysikalisk kemi; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Iron ore green pellets are produced by agglomeration of moist magnetite concentrates. The quality of green pellets is essential for the transportability and metallurgical benefits of the final product. LÄS MER

  4. 3. Studies of artificial mass bias in isotopic measurements by inductively coupled plasma mass spectrometry

    Författare :Henrik Andrén; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Mass spectrometry, and especially inductively coupled plasma mass spectrometry (ICP-MS), suffers heavily from mass bias, or instrumental mass discrimination. The nett result of this effect is the preferential transmission, most often of heavier ions through the mass spectrometer. LÄS MER

  5. 4. Inductively coupled plasma mass spectrometry : fundamental studies

    Författare :Petra K. Appelblad; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Inductively coupled plasma mass spectrometry (ICP-MS) is in focus in this thesis. Fundamental studies of ICP double focusing magnetic sector MS are presented, and some possible applications are discussed. LÄS MER

  7. 5. A spectroscopic study of mechanically activated sulphide minerals

    Författare :Benoit Drouet; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Sulphide minerals are a major source of non-ferrous metals such as lead, zinc or copper. Ores are processed to be selectively separated which can be achieved by flotation. LÄS MER
