  1. 1. Sediment remediation using activated carbon: amending knowledge gaps

    Author : Robert A. Rämö; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Barbara Beckingham; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; sediment contamination; sediment remediation; sorbent amendment; activated carbon; benthic community; macroinvertebrates; Baltic Sea; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Many coastal sediments have accumulated large quantities of contaminants from past anthropogenic activities and now act as a secondary emission source of legacy pollutants to coastal ecosystems. New sediment remediation strategies are needed to address widespread sediment pollution. READ MORE

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

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

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

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

    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

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

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

    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

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

    Author : Åsa Edell; Chalmers University of Technology; []
    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
