  • Removal of Lead from Gasoline

    On 12th March 1997, the European Commission adopted a proposal from the Environment Commissioner Ritt Bjerregaard on a European Union strategy to combat acidification. The strategy will, by 2010, reduce significantly the extent of the areas in the European Union where the tolerance of sensitive ecosystems to acidity is exceeded. Main elements of the strategy include establishment of national ...

  • Airport Lead and Arsenic Removal - Case Study

    City of Cincinnati The Airport was built on a former military firing range and apple orchard. To complete the removal of all the lead and arsenic, we excavated and removed over 20,000 tons of treated and non-treated contaminated soil. Then we stabilized 11,000 tons of hazardous soil on site. We graded and capped the site all while complying with FAA, City and Airport ...

  • Differences in the removal mechanisms of Undaria pinnatifida and Phragmites australis as biomaterials for lead removal

    This study offers the opportunity to utilize Undaria pinnatifida and Phragmites australis to remove lead from water in permeable reactive barrier (PRB) technology. Its efficacy was tested using batch experiments and PRB column systems. From the batch experiment results, a higher adsorption capacity was observed for Undaria pinnatifida. Nevertheless, ...

  • Removal of lead and chromium from aqueous solution by bacillus circulans biofilm

    Contamination of the aquatic environment by heavy metals is a worldwide environmental problem. The pollutants of serious concern include lead, chromium, mercury, uranium, selenium, zinc, arsenic, cadmium, gold, silver, copper and nickel, due to their arcinogenic and mutagenic nature (Leung et al., 2000). Many industries such as coating, automotive, aeronautical, steel, textile dyeing, leather ...

  • Characterization of air plasma-activated carbon nanotube electrodes for the removal of lead ion

    Carbon nanotube electrodes were prepared by pressing a mixture of carbon nanotubes and polytetrafluoroethylene (which acted as a binder) on a stainless steel net collector, and the electrodes were subsequently activated in our self-designed plasma apparatus, using air plasma. The morphology and surface functional groups of the electrodes were characterized using scanning electron microscopy and ...

  • Removal of lead from aqueous solutions by complexation ultrafiltration with chitosan

    The removal of lead from aqueous dilute solutions by complexation-ultrafiltration with chitosan was studied. Experiments were performed as a function of aqueous pH, chitosan/Pb2+ ratio, and background electrolyte concentration. The value of pH was found to be the most important parameter to effect the lead removal. The lead removal rate reaches the plateau at almost 100% when the chitosan and ...

  • Adsorptive removal studies of lead(II) ions using functionalized silica

    An adsorbent was prepared by the functionalization of 2-hydroxyacetophenone-3-thiosemicarbazone onto 3-aminopropyl silica by diazotation and characterized by Fourier transmission infra red spectrometry. The functionalized silica was evaluated for removal of lead(II) ions in aqueous solutions. The maximum adsorption capacity 385 μg/g was obtained with an initial concentration of 1,000 μg/L by the ...

  • Efficiency Removal of Phenol, Lead and Cadmium by means of UV/TiO2/H2O2 Processes

    A variety of processes can be used in treatment of industrial wastewaters. The relatively newest of which is photo catalysis with titanium dioxide which may also be used plus hydrogen peroxide to improve the treatment rate. In this study, photo catalysis/ hydrogen peroxide processes had been employed for the removal of phenol, lead and cadmium by three different pHs of 3.5, 7 and 11. The ...

  • Removal of cadmium, chromium, copper, lead and zinc ions by alisma plantago aquatica

    Heavy metals are major toxic pollutants with severe health effects on humans. They are released into the environment from a variety of industrial activities. Alisma plantago aquatica (APA) was used as adsorbent to remove Cd(II), Pb (II), Zn(II) Cr(III) and Cu(II) from aqueous solution. The batch kinetic studies revealed that the adsorption was influenced by initial pH, concentration and ...

  • LegalLookout: EPA Proposes Lead-Based Paint Removal Requirements

    On Jan 10, 2006, EPA proposed extensive requirements to minimize the introduction of lead hazards resulting from the disturbance of lead-based paint during renovation, repair and painting activities in most housing built before 1978.[1] The proposal supports the attainment of the federal government’s goal of eliminating childhood lead poisoning by 2010. Importantly for Pollution Engineering ...

  • Lead removal efficiency using biosorbents as alternative materials for permeable reactive barriers

    As alternative materials for heavy metal removal, this study investigated biosorbents to determine their suitability for permeable reactive barriers. The lead removal efficiencies of brown seaweed (Undaria pinnatifida) and reed (Phragmites australis) were determined under different conditions (batch and column system). The experimental results for these biomaterials fitted ...
