  1. 1. Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on bis-triazine-bipyrididine (BTBP)-class Ligands

    Författare :Elin Löfström Engdahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Used nuclear fuel; Density; Solvent; Extraction vs. time; BTBP; GANEX; Liquid-Liquid Extraction; Interfacial tension; Diluent;

    Sammanfattning : Used nuclear fuel taken directly from a reactor is radiotoxic for mankind and its environment for a long time. One of the major contributions to the long time radiotoxicity is the presence of a group of elements called the actinides. LÄS MER

  3. 2. The influence of Diluents and Side Groups of the Ligands on Liquid-Liquid Extraction of Actinides and Lanthanides

    Författare :Teodora Retegan Vollmer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Am; side group; radionuclides; liquid-liquid extraction; Eu; irradiation; diluents.;

    Sammanfattning : Fossil fuels are no longer a choice for energy production, both because of their diminishing availability and the bi-products of their combustion processes. A possibility to replace the fossil fuels would be utilization of nuclear power. No green-house gases are produced, but as any industry, it generates wastes. LÄS MER

  4. 3. New directions in non-porous membrane extraction

    Författare :Eddie Thordarson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extracting syringe; solvent-free; miniaturisation; micro-porous membrane liquid-liquid extraction; polymeric membrane extraction; Non-porous membrane extraction; supported liquid extraction; integration; automation; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Complex biological and environmental samples require a high degree of selectivity in order to determine components therein. Sensitivity measures, such as analyte pre-concentration are often required for assessing composition quantitatively. LÄS MER

  5. 4. A Novel Miniaturised Dynamic Hollow-Fibre Liquid-Phase Micro-Extraction Method for Xenobiotics in Human Plasma Samples

    Författare :Helena Hansson; Ulrika Nilsson; Bo Karlberg; Peter Haglund; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sample clean-up; human blood plasma; hollow-fibre liquid phase microextraction; supported liquid membrane extraction; SLM; HF-LPME; sample preparation; bioanalysis; liquid-liquid extraction; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Bioanalytical chemistry is a challenging field, often involving complex samples, such as blood, plasma, serum or urine. In many applications, sample cleanup is the most demanding and time-consuming step. LÄS MER
