  1. 16. Solvent adsorption in SFC : Adsorption of methanol under supercritical conditions

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Author : Emelie Edström; [2015]
    Keywords : SFC; excess adsorption isotherm; methanol; tracer pulse;

    Abstract : Chromatography is a widely used separation technique including many different modes, for example supercritical fluid chromatography (SFC) which uses a supercritical fluid as mobile phase. A supercritical fluid is achieved when a substance is subjected to a temperature and pressure above the critical point and the boundary between the liquid phase and gas phase is erased. READ MORE

  3. 17. Acid neutralization using steel slags : Adsorption of fluorides in solutions using AOD slags

    University essay from KTH/Materialvetenskap

    Author : Jesper Larsson; [2015]
    Keywords : acid neutralization; AOD slag; fluoride adsorption; syraneutralisering; AOD slagg; fluoradsorption;

    Abstract : Surface treatment processes of stainless steel, such as pickling, produces acidic waste water consisting of Na⁺, Cl⁻, F⁻, NO⁻3, SO42-, PO43-, Fe3+, Cr6+ and Ni2+. At Sandvik ABs steel works in Sandviken, this waste water is treated and neutralized using slaked lime before being released into the lake Storsjön. READ MORE

  4. 18. Coating fine particles

    University essay from Uppsala universitet/Institutionen för kemi - Ångström

    Author : Bergqvist Andrea; [2014]
    Keywords : ;

    Abstract : Controlled release of an active is used in many applications. An example is drug delivery were it is desirable to release the active substance close to the target. In paints can anti-mold substances be encapsulated and released slowly during a long time which can extend the lifetime of the paint. READ MORE

  5. 19. Phosphorus Removal and Methylene Blue Adsorption by Porous Calcium Silicate Hydrate.

    University essay from KTH/Mark- och vattenteknik

    Author : Asanka Welagedara; [2013]
    Keywords : Absol; Batch experiment; Sorption capacity; Adsorption kinetic; ;

    Abstract : Nutrients (nitrogen and phosphorus) should be removed and recycled from wastewater in order to reduce the nutrient load to recipient waters, avoiding contamination of groundwater and conserve resources. There is a need to pay more attention to phosphorus (P) removal and recycling from wastewater due to limited availability of phosphorus recourses. READ MORE

  6. 20. Adsorption Chillers : uptake of Ethanol on Type RD Silica gel

    University essay from Energisystem; Tekniska högskolan

    Author : Joel Arnoldsson; [2012]
    Keywords : Adsorption; ethanol; silica gel; experiment;

    Abstract : The adsorption cooling technology has the potential to replace all vapor compression based chillers in the future. So, in all over the world immense researches are going on in this field. The purpose of this report is to experimentally investigate whether ethanol could serve as a refrigerant in the technology.
