  5. 3. 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.

    Abstract : In many countries over the world (including Sweden), metal toxicity in freshwater resources causes a severe drinking water quality problem and poses a threat to the environment and human health. Among the different toxic metals in the water resources of Sweden, arsenic and uranium are the biggest threats to health. READ MORE

  7. 5. 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
