  2. 1. Microbial Treatment of Heavy Metal Leachates

    Author : Teresa Alvarez Aliaga; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; algal-bacterial symbiosis.; metal precipitation; biosorption; biogenic sulphide; municipal and agricultural solid wastes organic matter degradation; sulphate-reducing bacteria; Bioremediation; heavy metals removal; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

    Abstract : Ore-mining, metallurgy and other industrial activities represent the source of heavy metal and radionuclide contamination in terrestrial and aquatic environments. Physico-chemical processes are employed for heavy metal removal from industrial wastewater. 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. Equilibrium and Kinetic Batch Studies of Cadmium and Lead sorption using Low Cost Biosorbents

    Author : Grace Bakyayita Kizito; Ann-Catrine Norrström; Robinah Kulabako; Mai Nalubega; Dan Berggren Kleja; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biosorbents; cadmium; chemisorption; isotherms; kinetics; lead;

    Abstract : Agricultural wastes; Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were evaluated for uptake of aqueous Cd2+ and Pb2+ ions in single- and binary-component solutions. Untreated, base-treated and peroxide-treated biomasses were employed in batch studies. READ MORE
