  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Chemical adsorption of oxytetracycline from aqueous solution by modified molecular sieves

    The removal of oxytetracycline (OTC) from aqueous solution on modified molecular sieve via adsorption was investigated in the present work. The copper(II) modified molecular sieve had the much higher adsorbed amount than unmodified one. The bigger pore, the more adsorption sites benefitted for the adsorbed amount of OTC. The exchanged amount of copper(II) and the acid-base property of solution ...

  • Mg/Al double-metal hydroxide regeneration of anion exchange resin by electric field intensification

    Fouled anion exchange resins were regenerated by electric field intensification of Mg/Al double-metal hydroxides. Regenerative experiments were performed with varying voltages (10–30 V) and dosages of Mg/Al hydroxides (0.045–0.135 mol and 0.015–0.045 mol, respectively) for 1–5 h. Optimal results were obtained under the following regenerative conditions: 20 V, 4 h, and 0.09/0.03 mol of Mg/Al ...

  • Occurrence of heavy metals and contaminants on the surface of adjacent rivers

    Water is fundamental to the survival of living beings. It registers every impact and can function as an indicator of environmental stressors. Our objective in the current study was to assess the sanitary conditions of the waters in the Açude, Maria Lucinda and Santa Rosa streams. This was done by checking pH, running quantitative analyses of heavy metals and testing for total coliforms. The ...

  • Case Study - Monitoring Natural Attenuation - Catalonia, Spain

    Researchers at Universitat de Barcelona and University of Waterloo made use of EnviroInsite's advanced data visualization capabilities to contour hot-spots of TCE contamination and carbon isotopes. The results from multi-level sampling devices were then shown on a x-section to illustrate the loss of PCE in the direction of flow and variability of PCE and TCE isotopes vertically across the ...

  • Heavy Metal Compliance per RoHS Directive - Case Study

    Background Compliance with RoHS (or the Restriction of Hazardous Substances Directive) is an important issue in manufacturing today. RoHS has been constantly evolving since its original adoption in the EU as RoHS 2002/95/EC in 2003. Its full name is “Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment.” As the ...


  • Preparation and characterization of iron-copper binary oxide and its effective removal of antimony(III) from aqueous solution

    An Fe-Cu binary oxide was fabricated through a simple co-precipitation process, and was used to remove Sb(III) from aqueous solution. X-ray diffraction, scanning electron microscopy, energy dispersive X-ray and N2 adsorption–desorption measurements demonstrated that the Fe-Cu binary oxide consisted of poorly ordered ferrihydrite and CuO, and its specific surface area was higher than both iron ...

  • Analysis of Highly Mineralized Aqueous Solutions by ICP-AES

    Environmental Inductively Coupled Plasma (ICP) methods, such as EPA 200.7 or SW846 Method 6010, expect that samples will be fairly dilute without an overabundance of dissolved constituents (less than 2000 ppm Total Dissolved Solids). Laboratories running mine-impacted waters, such as acid rock drainage from exposed copper tailings, or mineral digests of a “waste” sample (that is ...

  • Case study - Sheet metal fabrication & surface wipe analysis

    A manufacturing company uses cutting oils to produce sheet metal to assemble elevators. The metal must be cleaned after production. Wipe samples were collected by the client and sent to Sitelab to monitor and adjust a new cleaning system ...

  • Removal of trivalent metal ions from aqueous solution via cross-flow ultrafiltration system using zeolite membranes

    This study aimed to assess the performance of three zeolite membranes in the removal of trivalent metal ions from aqueous solution using a cross-flow mode of operation. Three types of zeolite membrane, MCM-41, MCM-48 and FAU, were prepared on a low-cost, circular ceramic support by hydrothermal treatment. The three zeolite membranes were characterized by using X-ray diffraction (XRD), field ...

  • Bioaccessibility tests accurately estimate bioavailability of lead to quail

    Hazards of soil‐borne Pb to wild birds may be more accurately quantified if the bioavailability of that Pb is known. To better understand the bioavailability of Pb to birds, we measured blood Pb concentrations in Japanese quail (Coturnix japonica) fed diets containing Pb‐contaminated soils. Relative bioavailabilities were expressed by comparison with blood Pb concentrations in quail fed a Pb ...

  • Metals‐mediated climate susceptibility in a warming world: Larval and latent effects on a model amphibian

    Though sophisticated models predict the effects of future temperatures on ectotherms, few also address how ubiquitous sublethal contaminants alter an organism's response to thermal stress. In ectotherms, higher metabolic rates from warming temperatures can beneficially speed metabolism and development. If compounded by chronic, sublethal pollution, additional resource demands for elimination ...
