  1. 1. Modeling adsorption of organic compounds on activated carbon a multivariate approach

    University dissertation from Umeå : Kemi

    Author : Jufang Wu; Anders Cedergren; Ingrid Fängmark; Ola Claesson; Lars-Gunnar Hammarström; Fritz Stoeckli; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; activated carbon; adsorption; adsorption capacity; adsorption rate; PCA; PLS; binary mixtures; Dubinin-Radushkevich; Wheeler-Jonas; Analytisk kemi; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Abstract : Activated carbon is an adsorbent that is commonly used for removing organic contaminants from air due to its abundant pores and large internal surface area. This thesis is concerned with the static adsorption capacity and adsorption kinetics for single and binary organic compounds on different types of activated carbon. READ MORE

  2. 2. Towards application of activated carbon treatment for pharmaceutical removal in municipal wastewater

    University dissertation from Umeå : Kemi

    Author : Victor Kårelid; Gen Larsson; Gunno Renman; Ola Svahn; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced wastewater treatment; granular activated carbon; powdered activated carbon; municipal wastewater treatment; pharmaceutical removal; Biotechnology; Bioteknologi;

    Abstract : Many pharmaceuticals are found in municipal wastewater effluents due to their persistence in the human body as well as in conventional wastewater treatment processes. This discharge to the environment can lead to adverse effects in aquatic species, such as feminization of male fish. READ MORE

  3. 3. Refining of hydrochars/ hydrothermally carbonized biomass into activated carbons and their applications

    University dissertation from Umeå : Kemi

    Author : Wenming Hao; Niklas Hedin; Robert Mokaya; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrothermally carbonized biomass; activated carbon; full factorial design; activated carbon disc; nanoparticles; iron oxide; CO2 separation; methylene blue; adsorption; materialkemi; Materials Chemistry;

    Abstract : Hydrothermally treated biomass could not only be used as a fuel or a fertilizer but it can also be refined into high-value products. Activated carbons are one of those. READ MORE

  4. 4. Effects of Natural Organic Matter on Herbicide Adsorption to Activated Carbon

    University dissertation from Umeå : Kemi

    Author : Åsa Edell; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural organic matter; herbicide; adsorption isotherm; preloading; activated carbon; competitive interaction;

    Abstract : The presence of pesticides in the aquatic environment represents a potential threat to water quality and human health. Increasingly stringent drinking water quality directives focus on the need for efficient pesticide removal processes. READ MORE

  5. 5. Three-dimensional structured carbon foam synthesis and applications

    University dissertation from Umeå : Umeå University

    Author : Ngoc Tung Pham; Jyri-Pekka Mikkola; Krisztian Kordas; William Siljebo; Dmitry Yu. Murzin; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon foam; melamine foam; absorbent; water purification; heterogeneous catalyst; catalyst support; SpinChem®; rotating bed reactor; water electrolysis; energy conversion;

    Abstract : Recently, due to the unique properties and structures such as large geometric surface area, electrical conductivity and light weight, 3D structured carbon materials have been attracting extensive attention from scientists. Moreover, the materials, which can provide well-defined pathways for reactants to easily access active sites, are extremely useful for energy conversion as well as environmental and catalysis applications.
