Development of teawaste based bio-sorbent materials for removal of Cr(VI) from wastewater
… of the ecological environment. Hexavalent chromium in industrial waste water is a common typical heavy metal ion. Therefore, how to effectively treat heavy metal pollution in water has become a hot topic in the field of water pollution control. <br/><br/>In this research bio-sorbent …

Metal contamination and methane oxidising bacteria around a formerly industrialised suburban river.
… (Bath) was also able to remediate hexavalent chromium contamination. In the current study sediment samples were enriched from an urban river in Sheffield in Northern England that has previously suffered serious heavy metal pollution due to previous activity of the steel industry (17th to 19th …

Surface chemistry design and characterization of anion exchange and activated carbon fibers for critical contaminants removal
… a novel fibrous platform for rapid and selective removal of trace contaminants. The first project is to study activated carbon fiber composites (ACFCs) for removal of NH3 from air. Three series of materials were synthesized and modified, namely Polyvinyl alcohol (PVA) based Chemically Activated …

Formation and Characterisation of Nanostructured Polypyrrole Films: Their Growth on Membrane Supports and Application in Heavy Metal Remediation
… including heavy metals. These include chromium, nickel, lead, zinc and arsenic. The natural concentrations of these metals in water vary depending on the metal content of the surroundings, but they may also enter the environment from a range of anthropogenic sources. Chromium for …

Exploring Bioelectrochemical Systems for Removal and Recovery of Hexavalent Chromium or Nutrients
… the potential to remove and recover hexavalent Chromium from synthetic wastewater, and ammonia and phosphate from digested manure. The BES was able to achieve 99.6% removal of Chromium by membrane adsorption in 5 days but failed to recover in the concentration chamber. Nutrients were removed …
