  1. 1. Double-layer vs single-layer cryogels as a dye affinity chromatography column, comparison study

    University essay from Lunds universitet/Kemiska institutionen

    Author : Thi Hoai Thu Trinh; [2022]
    Keywords : dye-affinity chromatography; single-layer cryogels; double-layer cryogels; protein purification; bovine serum albumin; biochemistry; Chemistry;

    Abstract : Dye affinity chromatography is one of the chromatography techniques which uses dye as a ligand for protein purification. In this study, single-layer poly(acrylamide-allyl glycidyl ether) cryogel was prepared, which contains free epoxy groups at sub-zero temperature. READ MORE

  2. 2. Modeling transport phenomena with COMSOL Multiphysics - Adsorptive membrane fouling in lignocellulosic biorefineries and lessons learned from it

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Linnéa Petersson; [2020]
    Keywords : QCM-D; Quartz crystal microbalance with dissipation monitoring; Hemicellulose; GGM; Galactoglucomannans; Adsorption; Membrane fouling; COMSOL; Chemical engineering; Kemiteknik; Technology and Engineering;

    Abstract : The separation of hemicelluloses, like glactoglucomannans, from lignocellulosic process streams is an important step in building profitable lignocellulosic biorefineries. The most common method for the separation is membrane filtration, however, it has the draw-back of being sensitive to membrane fouling. READ MORE

  3. 3. Kinetics of Swelling Applied on Gelatine

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Victor Norgren; [2015]
    Keywords : fluid dynamic gauging FDG ; gravimetric measurements; pseudo-sigmoidal model PSM ; pseudo-second order model; Ofner; Robinson; Hofmeister; gelatine; swelling; food engineering; livsmedelsteknik; bio-polymers; anisotropic material; Arrhenius equation; physical chemistry; photography; pharmaceutics; Agriculture and Food Sciences;

    Abstract : This report is about the measurements of swelling gelatine films of different thickness and at different temperature. The research has been mainly focused on finding a suitable model. Results have shown that the new Pseudo-Sigmoidal Model (PSM) is superior to previous quasi-second order models such as the Robinson and Ofner model. READ MORE

  4. 4. 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

  5. 5. 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
