  • Self-purification of marine environments for heavy metals: a study on removal of lead(II) and copper(II) by cuttlebone

    The aim of this study was to determine adsorption properties of cuttlebone, cuttlefish bone as dead biomass, for lead(II) and copper(II) from aqueous solutions. Adsorption kinetic, isotherm and effect of pH (in the range of 2.0–7.0) were investigated in a single component batch system at room temperature (25 ± 1 °C). The heavy metal adsorption by cuttlebone was relatively rapid ...

  • Efficiency of sugarcane bagasse-based sorbents for oil removal from engine washing wastewater

    This work evaluates the efficiency of sugarcane bagasse-based sorbents in the sorption of oil from engine washing wastewater. The sorbents were obtained from sugarcane bagasse in the natural form (SB-N) and modified with either acetic anhydride (SB-Acet) or 3-aminopropyltriethoxysilane (SB-APTS). The results showed that the sorption capacity of these materials decreased in the following order: ...

  • 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 ...

  • Three Strategic Options for Managing Acquired Environmental Liabilities

    Evaluating Through a Finance Lens As companies strive to remain competitive and profitable in today’s uncertain economy, asset transactions continue to play a leading role in their efforts to transform, adapt and re-invent themselves.

  • Removal of lead(II) and nickel(II) ions from aqueous solution via Bermuda grass biomass

    Adsorption of lead(II) and nickel(II) ions from aqueous solutions was investigated by Bermuda grass biomass. The adsorption process was studied as a function of pH, initial metal concentration, temperature and time. The experimental data obtained were investigated via Langmuir, Freundlich and Temkin isotherms. The kinetic data were examined by pseudo-second-order and intraparticle diffusion ...

  • Effective removal of lead (II) ions by dead calcareous skeletons: sorption performance and influencing factors

    Dead calcareous skeletons (CSs) as low-cost adsorbents were studied to remove lead ions (Pb (II)) in an aqueous solution. Factors influencing the efficiency of CSs were evaluated by adsorbent size, contact time, initial concentration, dosage concentration and pH. The optimum CS size for removal of Pb (II) was 710 μm at an equilibrium time of 720 min. The best dosage of CS was 10 g/L for a 99% ...

  • Preparation and application of magnetite nanoparticles immobilized on cellulose acetate nanofibers for lead removal from polluted water

    Novel magnetic cellulose acetate (CA) nanofibers were fabricated using an electrospinning process. Co-precipitated magnetite iron oxide nanoparticles were immobilized onto CA nanofibers at different weight ratios (0.2–2.5% wt/v) with a CA concentration of 15% (wt %), applied electric voltage of 20 kV, feeding rate of 1.5 ml/h and 7 cm distance between needle tip and collector. The prepared ...

  • The Use of Leading Indicators to Predict Safety Performance

    To find sources of leading safety indicators, we need to look at the base of the Heinrich Safety Pyramid. Leading safety indicators are derived from safety incidents that did not result in injury. These can include everything from job safety observations and attendance at safety meetings to unsafe acts and near misses. These are different than lagging indicators, which are statistics that result ...
