  2. 1. Removal and Recovery of Metals from Municipal Solid Waste Incineration ashes by a Hydrometallurgical Process

    Author : Jinfeng Tang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MSWI ash; Cyanex 572; leaching; zinc; Cyanex 923; solvent extraction; LIX860N-I; copper; mixer-settler;

    Abstract : Municipal Solid Waste Incineration (MSWI) fly ash contains significant amounts of leachable metals, and is therefore considered to be a hazardous waste. The increased amounts of fly ash generated cause environmental issues, management costs and accumulation of valuable metals in landfills. READ MORE

  4. 2. Adsorption behavior of heavy metal ions from aqueous medium on nanocellulose

    Author : Peng Liu; Lars Wågberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : The aim of this work was to explore the potential of nanocellulose, nanocellulose derivatives and nanochitin to remove metal ions from contaminated water. The above nano-polysaccharides were of interest in water purification technologies due to their high surface area and versatile surface chemistry. READ MORE

  5. 3. Metal-Chelate Complexes in Alkaline Solution : On Recovery Techniques and Cellulose-based Hybrid Material Synthesis

    Author : Alireza Eivazihollagh; Håkan Edlund; Magnus Norgren; Joakim Bäckström; Christian Ekberg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : For decades, aminopolycarboxylate chelating agents have been extensively used in various industrial applications. The ability of chelating agents to form stable metal-chelate complexes is the main reason for using them to manage metal ions within water-based industrial processes. READ MORE
