  1. 1. Calculating the combined elemental composition of spodumene using La_ICP_MS in thin_sections samples from Europe.

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Maximilian Körtge; [2023]
    Nyckelord :Lithium minerals; Spodumene; Trace-elements; La-ICP-MS; Mineral processing; Geochemistry;

    Sammanfattning : The study gives a broad background to understand the high demand of lithium batteries in the coming years, especially in Europe. The goal of the study is to use La-ICP-MS to analyse spodumene samples from different lithium deposits in Europe to get a better knowledge of the contents of trace elements in spodumene. LÄS MER

  3. 2. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Elina Fernö; [2023]
    Nyckelord :Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

    Sammanfattning : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. LÄS MER

  4. 3. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Elsa Muller; [2023]
    Nyckelord :Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

    Sammanfattning : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. LÄS MER

  5. 4. Investigation of Potentially Toxic Elements in Agriculture Soil : Greenhouse and Open-field Farming in Türkiye

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Furkan Özkan; [2023]
    Nyckelord :Agriculture; Fertilizer; Organic Farming; Potentially Toxic Elements PTE ; Tarım; Gübre; Organik Tarım; Potansiyel Toksik Elementler PTE;

    Sammanfattning : Greenhouse food production has intensive fertilizer practices, and it leads to contamination in the soil and food chains. This study investigated the potentially toxic elements (As, Pb, Zn, Cd, Cr, Cu, and Ni) (PTE) in agriculture soil and their bioaccumulation by dragon fruit and banana. LÄS MER

  7. 5. Tillverkning av kalibrerstandard förämnesbestämning i kärnbränslen

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Materialteori

    Författare :Isak Lundell; Sven Ekman; [2023]
    Nyckelord :kärnbränsle; kärnkemi; ICPMS; atomkraft; fissionsprodukter; transuran; simulerat bränsle;

    Sammanfattning : The test production of a simulated nuclear fuel, possible to use as a calibration standard was donethru dissolving the preferred dopant-metals in a nitric-salt into weak acid. This solution wasmixed with dissolved uranium-salt to aimed concentration. This was precipitated by rising pHforming metallic-hydroxide. LÄS MER
