  1. 1. Green Protein Hydrogels and Non-dry Aerogels in Water Purification

    University essay from KTH/Kemi

    Author : Emanuel Nelsson Vedung; Alexander Singh; Julia Wadefjord; [2022]
    Keywords : Aerogel; Hydrogel; Whey Protein Isolate; Water purification; Adsorption; Sustainability;

    Abstract : Having access to clean water is not a certainty for every human being. Today, there are major problems with polluted water that not just affect us humans, but also the ecosystem around us. In recent years, research into making aerogels from protein nanofibrils (PNF) has increased. READ MORE

  3. 2. Conductive metal-organic frameworks (MOFs) and possible applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Meghdad Hosseinzadegan; [2022]
    Keywords : ;

    Abstract : Metal-organic frameworks (MOFs) are a class of hybrid organic/inorganic materials with permanent porous structure. Whilst there are virtually endless possible selection of metal ions and organic ligands to build up a MOF structure, intrinsically conductive MOFs are rare, relatively new, and our knowledge on their conductivity and charge transport mechanisms is limited.

  4. 3. 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

  5. 4. Heavy metal removal and water treatment using Upsalite

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Philip Erenbo; [2017]
    Keywords : Upsalite; lead; cadmium; nickel; MgO3; heavy metal; water treatment;

    Abstract : Ion exchange reactions between Upsalite, a mesoporous magnesium carbonate, and metal ions of cadmium, lead and nickel have been studied to evaluate the capacities of Upsalite as a water treatment agent. Uptake capacity and reaction kinetics have been evaluated using a batch experiment and atomic absorption spectroscopy. READ MORE

  6. 5. Arsenic Removal From Flue Gas Condensate with Ferrihydrite Precipitation.

    University essay from KTH/Mark- och vattenteknik

    Author : Louise Waldenström; [2014]
    Keywords : Waste wood; Pressure-treated wood; Flue gas condensate; Arsenic removal by precipitation; Ferrihydrite; TMT 15;

    Abstract : At the Idbäcken combined heat and power (CHP) plant waste wood is combusted. The flue gas from the combustion is condensed and heavy metals and other toxic species ends up in the condensate water. READ MORE
