  • Heavy Metals Analysis

    Correct measurement results are a prerequisite for compliance with limit values, which are always specified as total metals. Heavy metals such as copper, nickel, zinc, etc. can be quickly and reliably determined in aqueous samples with the help of the LANGE cuvette tests. Matrix factors (e.g. interference ions, colour, turbidities, etc.) may have a negative impact on themeasurement and cause ...


  • Biosolids sampling and handling approaches for microbial analyses

     ABSTRACT The protection of human health and the environment while making the use of biosolids products more practical is a joint goal of utilities and regulatory agencies. Assuring the safety of biosolids is paramount to gaining wide public acceptance of this waste-to-beneficial use product. Making effective decisions about the safety of biosolids use relies on quality data. Satisfying ...

  • Metal alkoxides as molecular precursor for the synthesis of metal oxide nanomaterials

    A versatile, convenient and non-toxic wet chemical method was utilised for the synthesis of uniform and monodispersable high-tech metal oxide nanopowder with controlled functional properties via using oxo-metal alkoxide as a single source molecular precursor at low temperature. The powder was characterised by different analytical techniques. SEM-EDS analyses showed consistency with the ...

  • The metal binding potential of a dairy isolate

    Excess iron in water resources can lead to health hazards and problems. The ability of lactic acid bacteria to bind iron has not yet been widely studied. In the present study, sorption of iron ions from aqueous solutions onto lactic acid bacterium was determined. Elemental analyses were carried out by inductively coupled plasma optical emission spectrometry. The kinetics of Fe(III) biosorption ...

  • REDWAVE Metal Days 2015 - Review

    The REDWAVE Metal Days, at BT-Wolfgang Binder in Gleisdorf, pro­vided the context for international experts from various sectors of the metal and aluminium recycling in­dustry to exchange information on markets, technologies and practical experience. In addition, the new REDWAVE XRF-M sorting system, for recycling in the metals sector, was presented to the participants. ...

  • Air crash investigation using Oxford Instruments handheld analysers - case study

    It was late April 1945 during the last days of World War II for Italy. Just one week before the liberation of Italy from the fascists rule, a group of five Messerschmitt BF 109 planes took off from the Vicenza airbase heading to Ghedi, near Brescia. This was not a combat mission but a transfer flight. Soon after take-off the planes were intercepted by US fighters and attacked. All five planes ...

  • Atomic resolution analyses of nano-structured materials by atom probe tomography

    The three dimensional atom probe (3DAP) is a well established and widely used nanoanalysis tool in materials science (mainly metallic materials). Due to its ability to map out in 3D the distribution of atoms in the real space on a nearly atomic scale, it has been extensively applied for the investigation of a large variety of materials, allowing a better understanding of physical phenomena ...

  • Accumulation of heavy metals in the bottom sediments of the Irkutsk Reservoir

    The chemical composition of the bottom sediment, and more particularly the heavy metals content, reflects human developments and impacts on the catchment and reservoir's natural environment. The bottom sediments of the reservoir retained by the Irkutsk Dam have been analysed. The reservoir is mainly supplied by water from Lake Baikal. The following amounts of heavy metals have been found in the ...

  • Metal mixtures modeling evaluation: 1. Background

    Despite more than five decades of aquatic toxicity tests conducted with metal mixtures, there is still a need to understand how metals interact in mixtures and to predict their toxicity more accurately than currently is done. This paper provides a background for understanding the terminology, regulatory framework, qualitative and quantitative concepts, experimental approaches, and ...

  • Removal of heavy metals from aqueous solution by limestone

    This study focused on the removal of Pb(II), Cd(II), Cu(II), and Zn(II) using reagent solutions by natural limestone in a batch system. The sorbent, collected from the Late Cretaceous limestone beds, Tunisia, was characterised by X–ray diffraction (XRD), chemical analysis (XRF) and infrared spectroscopy (FTIR). XRF showed that the studied limestone contained high amount of calcium carbonates. XRD ...

  • Development of eco-efficiency in metal production in Finland

    In this article we reconsider if Eco-Efficiency (EE) is a suitable practical tool of Industrial Ecology (IE) to measure the progress towards Sustainable Development (SD) and the aims of IE. EE combines sparing use of natural resources with economic efficiency, the aim being reduced use of natural resources. Many scientific, government and international organisations consider EE an essential ...
