  2. 1. Removal of Inorganic Anionic Pollutants from Water using Adsorption Technology

    Author : Eva Kumar; William Hogland; Marcia Marques; Mika Sillanpää; Kenneth M. Persson; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water treatment; adsorption; inorganic anionic pollutants; granular ferric hydroxide GFH ; nano-alumina; adsorption isotherms; adsorption kinetics; modeling.; Miljövetenskap; Environmental Science; Environmental technology; Miljöteknik;

    Abstract : In the era of urbanization, industrialization and population growth, groundwater and drinking water sources are getting adversely polluted due to the addition of different toxic contaminants including inorganic anionic pollutants. The inorganic anions are of serious concern due to their adverse health effects on humans, even when present at very low concentrations in water. READ MORE

  4. 2. Structuring porous adsorbents and composites for gas separation and odor removal

    Author : Neda Keshavarzi; Lennart Bergström; Kurosch Rezwan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structure; pulsed current processing; zeolite; aluminophosphate; activated carbon; CO2 separation; adsorption; durability; cellulose; film; coating; Materials Chemistry; materialkemi;

    Abstract : Porous zeolite, carbon and aluminophosphate powders have been colloidally assembled and post-processed in the form of monoliths, flexible free standing films and coatings for gas separation and odor removal. Zeolite 13X monoliths with macroporosites up to 50 vol% and a high CO2 uptake were prepared by colloidal processing and sacrificial templating. READ MORE

  5. 3. Adsorption of dissolved organic matter in aquatic ecosystems : Effects on composition and reactivity

    Author : Marloes M. Groeneveld; Lars Tranvik; Dolly Kothawala; Suzanne Tank; Uppsala universitet; []
    Keywords : dissolved organic matter; DOM; carbon; aquatic; adsorption; mineral particles; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Inland waters receive organic matter from terrestrial ecosystems and in situ production. In transit from land to the ocean, dissolved organic carbon (DOC) may be mineralised to inorganic forms (CO2 and CH4) by microbial degradation and photodegradation. READ MORE

  6. 4. Alternative Adsorption Materials for Treatment of Contaminated Waters

    Author : Yuliya Kalmykova; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; Sphagnum peat; Heavy metals; Fiber ash;

    Abstract : The thesis presents a study of adsorbent materials for treatment of contaminated waters and remediation of contaminated soils. Natural and waste product materials showed high adsorption capacity for metals and organic pollutants and proved to be a good alternative to commercial adsorbents. READ MORE

  7. 5. Removal of metals from contaminated waters : Evaluating the use of synthetic adsorbents and green algae biomass

    Author : Roxana Quiroga Flores; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metals; toxicity; Adsorption; uptake; arsenic; cadmium; lead; methylmercury;

    Abstract : Metal contamination of water bodies has attracted global attention owing to its environmental toxicity, abundance and persistence. Metals such as arsenic, cadmium and mercury are of greater concern since they are toxic even at low concentrations. READ MORE
