2. 1. 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 : 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

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

   Author : Wenming Hao; Niklas Hedin; Robert Mokaya; Stockholms universitet; []
   Keywords : 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. 3. Effects of Natural Organic Matter on Herbicide Adsorption to Activated Carbon

   Author : Åsa Edell; Chalmers tekniska högskola; []
   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

6. 4. Tailoring residue-derived carbon materials for the removal of wastewater contaminants : adsorption and surface properties

   Author : Mirva Niinipuu; Stina Jansson; Jean-Francois Boily; Erik Rosenbaum; Magnus Bergknut; Capucine Dupont; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrochar; HTC; chemical activation; wastewater; pharmaceuticals; metals; surface properties; biobased residues;

   Abstract : The availability of effective, low-cost wastewater treatment is necessary for increased water recycling and the prevention of environmental pollution on a global scale. Adsorption on activated carbons is commonly applied in wastewater treatment, but the high cost of conventional activated carbons limits the use of this technique. READ MORE

7. 5. Adsorption and transformation of organic micropollutants in wastewater : New insights from 14C-labeling

   Author : Alexander Betsholtz; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated carbon; ozonation; Organic micropollutants; pharmaceuticals; wastewater; transformation products; biological degradation; GAC-filters; adsorption; 14C-labeling;

   Abstract : This thesis focuses on the removal of organic micropollutants and transformation products using ozone and activated carbon treatment processes. A combination of 14C-labeled and non-radiolabeled organic micropollutants was used to study aspects of micropollutant removal from novel perspectives. READ MORE
