  1. 26. Selective detection of TNT withmodified SERS-surfaces : Investigation of TNT adsorption and detection using goldand silver nano structured surfaces modified by cysteineand cysteamine

    University essay from Kemiska institutionen

    Author : Kristoffer Andersson; [2010]
    Keywords : ;

    Abstract : In the search for trace amounts of explosives in various environmental samples, the analytical procedure is in need of improvements. If it is for national security or for environmental purposes the detection of trace amounts of for example 2,4,6- trinitrotoluene (TNT) is a costly and time consuming procedure. READ MORE

  3. 27. Avskiljning av uran från dricksvatten med reaktiva filter

    University essay from SLU/Dept. of Soil Sciences

    Author : Ellinor Dässman; [2008]
    Keywords : uran; reaktiva filter; järnoxid; bergsborrade brunnar; jämviktsmodellering; Visual Minteq;

    Abstract : Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. READ MORE

  4. 28. Decomposition of Norway spruce needles and fine roots : production of CO2 and DOC

    University essay from SLU/Dept. of Soil and Environment

    Author : Hanna Larsson; [2008]
    Keywords : decomposition; CO2; DOC; needles; fine roots; carbon;

    Abstract : The relative amounts of CO2 and DOC lost during decomposition of spruce needles and fine roots are poorly known. However, knowledge about this division is crucial for our understanding of carbon cycling in boreal forest ecosystems. READ MORE

  5. 29. Low-cost adsorption materials for removal of metals from contaminated water.

    University essay from KTH/Mark- och vattenteknik

    Author : Richard Somerville; [2007]
    Keywords : Adsorption; Contaminated water; Low-cost material; Metal removal; Seaweed; Shrimp shell;

    Abstract : Batch equilibrium and dynamic column studies were undertaken to compare the metal-removal capabilities of two natural, low-cost materials (dried, crushed brown seaweed and shrimp shells) with a commercially available strong acid cation exchange resin (CER). All media maintained structural and hydraulic integrity over the duration of the column experiments. READ MORE

  6. 30. Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik

    University essay from SLU/Dept. of Soil Sciences

    Author : Frida Öhlund; [2007]
    Keywords : uran; riktvärde; vattenrening; membranfiltrering; jonbytesteknik; bäddvolymer; reningsgrad; Uppsala; Björklinge;

    Abstract : Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. READ MORE
