  1. 1. Development of Polyamide Solvent Extraction Reagents for Trivalent Lanthanides

    Författare :Mikhail S Tyumentsev; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyamides; Solvent Extraction; Europium; Rare Earth Elements; Lanthanides; Malonamides;

    Sammanfattning : Rare earth elements (REEs), including lanthanides, are critical materials for many industrial technologies. As a result recycling of end-of-life products containing REEs might be beneficial, as this could partially satisfy the growing demands of industry for these elements. LÄS MER

  3. 2. Tetradentate amide extraction agents for trivalent lanthanides

    Författare :Mikhail S Tyumentsev; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; malonamides; lanthanides; solvent extraction; entropic effect; electrospray ionization – mass spectrometry; single-crystal X-ray diffraction;

    Sammanfattning : Lanthanides are valuable materials. They are used in catalysts, permanent magnets, batteries, optical devices, and in many other products. Lanthanides are mainly supplied by mining industry, which generates large volumes of waste due to relatively low concentrations of these elements in geological deposits. LÄS MER
