  • How Not to Lose Cadmium While Measuring?

    Today cadmium finds a better usage than a hundred years ago. For example, metal cadmium plating is used for anticorrosion coatings that are more stable than zinc, nickel and tin-plated. Cadmium plating of steel parts gives greater resistance to corrosion, especially in sea water. About 20% of cadmium goes to the manufacture of cadmium electrodes used in ...

  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • Attached β-cyclodextrin/γ-(2,3-epoxypropoxy) propyl trimethoxysilane to graphene oxide and its application in copper removal

    The environmental applications of graphene oxide and β-cyclodextrin (β-CD) have attracted great attention since their first discovery. Novel nanocomposites were successfully prepared by using an esterification reaction between β-cyclodextrin/γ-(2,3-epoxypropoxy) propyl trimethoxysilane grafted graphene oxide (β-CD/GPTMS/GO). The β-CD/GPTMS/GO nanocomposites were used to remove the Cu2+ from ...

  • 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 ...

  • If lead ammunition is bad for people and the environment, why do we still use it?

    Concerns about regulation, skepticism about the science and misperceptions about costs are slowing the transition to nontoxic alternatives. Andrea Goodnight knows firsthand what lead poisoning looks like. A veterinarian at the Oakland Zoo, Goodnight treats endangered California condors when testing shows dangerous levels of the toxic metal in their blood. If ...

  • Adsorption of heavy metals from aqueous solutions by Mg–Al–Zn mingled oxides adsorbent

    In our study, Mg–Al–Zn mingled oxides were prepared by the co-precipitation method. The structure, composition, morphology and thermal stability of the synthesized Mg–Al–Zn mingled oxides were analyzed by powder X-ray diffraction, Fourier transform infrared spectrometry, N2 physisorption, scanning electron microscopy, differential scanning calorimetry and thermogravimetry. Batch experiments ...

  • 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 ...
