2. 1. 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

4. 2. Adsorption of Metallic Ions onto Chitosan : Equilibrium and Kinetic Studies

   Author : Martha Benavente; Joaquín Martínez; Olle Wahlberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; biosorption; chitin; heavy metals; isotherm; kinetic models; mining; speciation; water treatment; Chemical engineering; Kemiteknik;

   Abstract : Equilibrium isotherms and the adsorption kinetics of heavy metals onto chitosan were studied experimentally. Chitosan, a biopolymer produced from crustacean shells, has applications in various areas, particularly in drinking water and wastewater treatment due to its ability to remove metallic ions from solutions.

5. 3. Adsorption of Molecules on Metal Surfaces Studied by High Resolution Core Level Photoemission

   Author : Andreas Beutler; Synkrotronljusfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Core level photoemission; molecules; adsorption; single crystal surfaces; metals; metal films; vibrations of adsorbed molecules; surface ordering; carbon monoxide; photoelectron spectroscopy; surface diffusion; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1998:Beutler;

   Abstract : Various aspects of the adsorption of molecules on metal surfaces have been studied making use of different properties of high resolution core level photoemission. A thorough investigation has been performed of the ordering and the site occupancy of CO overlayers on Rh(111). CO has been shown to adsorb in on-top and three-fold-hollow sites. READ MORE

6. 4. Peat Coated with Iron Oxides : Purification of Metal(loid)-Contaminated Water and Treatment of the Spent Adsorbent

   Author : Alfreda Kasiuliene; Jurate Kumpiene; Ivan Carabante; Prosun Bhattacharya; Luke Beesly; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iron-peat; adsorption; arsenic; metals; combustion; hydrothermal carbonisation; landfilling; Avfallsteknik; Waste Science and Technology;

   Abstract : In Sweden due to the industrial activities, such as wood impregnation, multiple point sources of arsenic (As) contamination in soil and water bodies are scattered over the country. Metals, such as chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), cadmium (Cd) or zinc (Zn) at varying concentrations are usually present as well. 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
