  1. 1. Identification of Vanadium-Binding Ligands in White Wine

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Freja T Trybom; [2023]
    Keywords : Vanadium; LD converter slag; wine; food waste; recycling.;

    Abstract : Vanadin är en värdefull metall och kan lakas ur LD (Linz-Donawitz)-slagg med hjälp av vin. Ligander i vinet som lakar vanadin från LD-slagg studerades i denna rapport med mål att identifiera några av deras egenskaper såsom apparent molekylmassa och spektral information. READ MORE

  3. 2. Electrochemical oxidation of PFAS in soil conditions : Using Boron-doped diamond electrodes and iron electrodes

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Alexander Öhberg; [2022]
    Keywords : PFAS ELECTROCHEMICAL OXIDATION IN-SITU DESTRUCTION MINERALISATION REMOVAL;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) are a rising topic in the field of contaminated sites around the world, with destruction of these being an area in dire need of innovation. Previous experiments of destructive character have been proven efficient using boron doped diamond electrodes (BDD) in small scale electrochemical cells. READ MORE

  4. 3. Trace element leaching from alum shale fines and red ash from Kvarntorp during a large column test

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Helena Rydfjord; [2022]
    Keywords : Alum shale; Leachate; Trace elements; Kvarntorp;

    Abstract : Fuel shortage during the Second World War led to oil production in Kvarntorp, Kumla during 1942-1966 by pyrolyzing alum shale rich in pyrite, FeS2, and organic material such as kerogen. This production has led to a lot of waste laying deposited out in the open after the mining closed and has had negative environmental impact in the form of ongoing weathering and leaching of acidic water and leaching of trace elements into its surroundings.

  5. 4. Nanoplastic transport in soils by advection and bioturbation

    University essay from SLU/Dept. of Soil and Environment

    Author : Wiebke Mareile Heinze; [2019]
    Keywords : column leaching; attachment efficiency; exposure; mixing rates; modelling;

    Abstract : Micro- and nanoplastics are increasingly perceived as an emerging threat to ecosystems. They are emitted to soils through different pathways, including sewage sludge or compost applications in agriculture, or through tire abrasion and degradation of mismanaged waste. READ MORE

  6. 5. Evaluation of degree of phosphorus saturation (DPS) and easily soluble P in top- and subsoil as a predictor for P-leaching

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jessie Torpner; [2019]
    Keywords : degree of phosphorus saturation; dissolved reactive phosphorus; easily soluble P; column experiment; lactate extracted P;

    Abstract : Eutrophication has long been an environmental problem and the effects from fertilizingarable land is a known source. The degree of phosphorus saturation (DPS)and easily soluble phosphorus (P) are different variables used in different countriesto try to predict the leaching of P from soils. READ MORE
