  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

  3. 2. Fluoride removal by low-cost adsorbents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Fredrik Bernheim; [2022]
    Keywords : Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Abstract : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. READ MORE

  4. 3. Removal of per- and polyfluoroalkyl substances from drinking water using ozonation

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Miriam Dorothea Schäfers; [2017]
    Keywords : PFAS; drinking water; ozonation;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a broad group of man-made chemicals which are persistent, bioaccumulative and toxic. Due to their unique physicochemical properties PFASs are used in various industrial processes and consumer products. READ MORE

  5. 4. Phosphorus and Nitrogen Removalin Modified Biochar Filters

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ylva Stenström; [2017]
    Keywords : biochar; modified biochar; phosphorus filter; wastewater; batch adsorption experiment; nitrogen filter; COD; Tot-P; Tot-N; biokol; impregnerat biokol; fosforfilter; avloppsvatten; skakexperiment; kvävefilter; COD; Tot-P; Tot-N;

    Abstract : Onsite wastewater treatment systems in Sweden are getting old and many of them lack sufficient phosphorus, nitrogen and organic carbon reduction. Biochar is a material that has been suggested as an alternative to the common sand or soil used in onsite wastewater treatment systems. READ MORE

  6. 5. A Freundlich-based model for prediction of pH-dependent sulfate adsorption in forest soil.

    University essay from KTH/Mark- och vattenteknik

    Author : Muhammad Akram; [2015]
    Keywords : Sulfate; Spodosols; pH Dependent Sulfate Adsorption; Extended Freundlich Model;

    Abstract : The period of industrialization after the second World War in Europe released SO2 and NOx by combustion of fossil fuels and contributed the formation of S and N compounds in the forest ecosystem. The Swedish forest soil systems were influenced by emissions of SO2 followed by H2SO4 deposition, consequently the pool of SO42- had increased in the forest ecosystem. READ MORE
