  1. 1. Impact of Peroxide Speciation on the Kinetics of Oxidative Dissolution of UO2

    University essay from KTH/Kemi

    Author : Hazal Aydogan; [2022]
    Keywords : Spent nuclear fuel; H2O2; HCO3-; Speciation; Kinetics; Använt kärnbränsle; H2O2; HCO3-; Speciering; Kinetik;

    Abstract : Slutförvaring av använt kärnbränsle måste vara säker under 100 000 år eller mer för att förhindra att miljön skadas och att människor påverkas av långlivade radionuklider. Även om anläggningar för geologiskt djupförvar är utformade för att vara hållbara i många år, kan använt kärnbränsle komma i kontakt med grundvattnet i händelse av att flera barriärer brister.

  3. 2. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  4. 3. Risk estimation of multi-polluted soils in contact with lacustrine systems

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Gustav Hederfeld; [2018]
    Keywords : ;

    Abstract : The area of "Norra Hamnstaden" in Lidköping has been used for several different industires for more than 100 years and porcelain has been produced there since 1912. The sub-area studied in this thesis has been used as a landfill for industrial waste including waste from the local porcelain factory, Rörstrand. READ MORE

  5. 4. The matrix dependent solubility and speciation of mercury

    University essay from Örebro universitet/Institutionen för naturvetenskap

    Author : Erik Hagelberg; [2006]
    Keywords : mercury solubility speciation elemental matrix composition; kvicksilver löslighet speciering elementärt matris sammansättning;

    Abstract : The Swedish government has decided that waste containing more than 0.1% mercury is to be placed in a permanent repository in the bedrock1,10. To minimize the risk of spreading mercury, elemental mercury must first be converted into a practically insoluble compound. READ MORE
