  • Using EDXRF to quantify the amount of Metals in Asphalt Binders

    This article reviews these sources and proposes a scheme for measuring and quantifying the amounts of metals in their source materials used to bind asphalt used in making roads. The use of bench top EDXRF to characterize binders before blending them into asphalt cements is possible because the metal values are in the 10s – 1000s of ppms and are readily monitored. ...

  • Quantitative Analysis of Fluorine (9F) by EDXRF

      Fluorine compounds possess a wide range of properties, including flame retardance, water repellency, anti-fouling property, and heat resistance, and are therefore used in a wide range of fields from articles for everyday use to semiconductors. However, since the 1980s, the problems of global warming and ozone depletion in addition to the potential for bioaccumulation have led to ...

  • EDXRF Analysis of Sulfur and Other Elements in Oil

    The concentrations of sulfur substances in fuel oil, which greatly contribute to air pollution and acid rain, are regulated by law in many countries, and these regulations are becoming stricter with the growing concern about their impact on the environment and the consequences for society. Here, using the easy-to-operate EDX-720 energy dispersive X-ray fluorescence spectrometer, we determined the ...

  • The influence of past metallurgical activity on the concentration of heavy metals in the soil/grass system in Sibenik (Croatia)

    Degree of heavy metal pollution in soil caused by a former Ferromanganese Plant (FMP) and aluminium factory was investigated and the potential of metal mobility and bioavailability was estimated. Elemental concentrations in soil, vegetation and soil extracts were determined by EDXRF. In the nearest vicinity of the factory, soil concentrations ranged as follows: Mn 12,700-342,000 ppm, Zn 200-1090, ...
