2. 1. 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

4. 2. Water treatment using cryogel-based adsorbents - Targeting environmental pollutants at low concentrations

   Author : Linda Önnby; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; cryogels; nanoparticles; arsenic; cadmium; water treatment; composites;

   Abstract : The lack of safe, clean water is strongly linked to poverty, underdevelopment and poor health. Water is needed not only to sustain life, but to produce food and in industrial processes. Anthropogenic pollution and natural events can jeopardize access to safe water. READ MORE

5. 3. Modeling of glyphosate and metal-glyphosate speciation in solution and at solution-mineral interfaces

   Author : Caroline Jonsson; Staffan Sjöberg; Per Persson; Bernd Nowack; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; herbicide; glyphosate; surface complexation model; speciation; goethite; aged gamma-alumina; bayerite; manganite; cadmium II ; aluminium III ; potentiometric titration; adsorption; Chemistry; Kemi;

   Abstract : Glyphosate (N-(phosphonomethyl)glycine, PMG, H3L) is a widely used organophosphorous herbicide. It interacts with metal ions and mineral surfaces, which may affect its mobility, degradation and bioavailability in the environment. However, these interactions are far from fully understood.

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. Sludge-derived char : utilisation as a metal sorbent in dilute wastewaters

   Author : Ida Sylwan; Eva Thorin; Lena Johansson Westholm; Konrad Koch; Mälardalens universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; adsorption; sludge; biosolids; metal; wastewater treatment; sorption; adsorption; slam; metaller; avloppsvattenrening; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Metal concentrations in soil and water have increased since the Industrial Revolution, which may have negative health and environmental effects. Metal pollution occurs, for instance, in municipal wastewater, industrial wastewater, and stormwater. Concentrations are often low, due to dilution. A common technology for metal removal is sorption.
