    University essay from KTH/Kemiteknik

    Author : Caroline Kihlbom; [2021]
    Keywords : Solvent extraction; cobalt-nickel separation; CYANEX 272; pregnant leach solution; cobalt sulphate; Vätskevätskeextraktion; kobolt-nickel separation; CYANEX 272; laklösning; koboltsulfa;

    Abstract : This project aimed to examine the separation of cobalt and nickel using solvent extraction (SX) with the extractant CYANEX 272 (C272). It was intended to investigate the Co-Ni separation in a sulphate-based leach solution in presence of other contaminants. READ MORE

  3. 2. Solvent extraction of antimony and tin from speiss leachate

    University essay from Luleå tekniska universitet/Kemiteknik

    Author : Oscar Sundell; [2017]
    Keywords : Solvent extraction; tributyl phosphate; speiss; antimony; tin; bachelors thesis; chemical engineering;

    Abstract : This work is a cooperation with Boliden Minerals AB, who recently has been interested in recovering more valuable elements from their byproducts. For this case, solvent extraction was chosen as a potential method of recovering these valuables, as it is a method considered to be ideal for separation of trace elements from large amounts of other substances.

  4. 3. Perfluoroalkyl substances (PFASs), flame retardants and cyclic volatile methylsiloxanes in indoor air in Uppsala, Sweden : occurrence and human exposure assessment

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Bo Sha; [2017]
    Keywords : passive air sampling; SIPs; indoor air; PFAS; flame retardants; siloxanes; human exposure;

    Abstract : Indoor air samples were collected from three buildings located at the Swedish University of Agricultural Science (SLU) campus in Ultuna, Uppsala, Sweden and from residences of nine volunteers working in the three buildings. Sorbent-impregnated polyurethane foam (SIP) disk passive air samplers were deployed in different types of rooms in the three buildings including computer room (n = 1), labs (n = 3), lecture rooms (n = 3), offices (n = 8) and dining areas (n = 3) and homes (n = 9) of the volunteers between September and November in 2016.
