  3. 17. Molecular-level controls on water and organics intercalation in layered minerals

    Författare :Jerry Lindholm; Michael Holmboe; Jean-Francois Boily; Virginie Marry; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Minerals; Dynamic Vapor Sorption; montmorillonite; XRD; adsorption model; intercalation;

    Sammanfattning : Layered minerals are naturally abundant and often display a large surface area in relation to their weight. For swelling layered minerals, most of this area is contained between the layers in the interlayer space. LÄS MER

    Sammanfattning : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. LÄS MER

  5. 19. Adsorption behavior of heavy metal ions from aqueous medium on nanocellulose

    Författare :Peng Liu; Lars Wågberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : The aim of this work was to explore the potential of nanocellulose, nanocellulose derivatives and nanochitin to remove metal ions from contaminated water. The above nano-polysaccharides were of interest in water purification technologies due to their high surface area and versatile surface chemistry. LÄS MER

  7. 20. Thin films of molecular sieves : synthesis and applications

    Författare :Jonas Hedlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The seed film method for synthesis of ultra thin and thin molecular sieve films was developed. The versatility of the method was demonstrated by successful preparation of films of a number of molecular sieves (silicate-1, ZSM-5, NA) on various supports (silicon, alumina, gold, etc.). LÄS MER
