  1. 1. Fluoride removal by low-cost adsorbents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Fredrik Bernheim; [2022]
    Keywords : Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Abstract : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. READ MORE

  3. 2. Characterization of phases in Argon Oxygen Decarburization slag

    University essay from KTH/Materialvetenskap

    Author : Emil Rosqvist; Theodore Vassi; [2021]
    Keywords : ;

    Abstract : Slag is an important part of steelmaking with the AOD (Argon Oxygen Decarburization) process. In this work the focus was on developing a methodology for characterizing phases in slagsamples obtained after decarburization, reduction and desulphurization. READ MORE

  4. 3. Adsorption of Zn, Cd, V, Ba, Cu, Mo, Ni, Cr, Li and Pb to silicon and aluminium reduced AOD-slag

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Edvin Elmroth; [2018]
    Keywords : Steel slag; AOD; Si- and Al-reduced slag; Metal adsorption;

    Abstract : During production of steel, slag is formed as a by-product. The process of steelmaking involves usage of additives such as chromium or vanadium as reactants to optimize and produce high quality steel. Vast amounts of slag are formed and there is a continuous search for applications that can make good use of the slag. READ MORE
