Trace Elements Analysis Articles

  • What is the best way to do trace metal sampling?

    All samplers contaminate or distort in some way. • Plastics may leach metals from ultraviolet inhibitors, metal-organic plasticizers, (rarely) metal catalysts. • Teflon has a rough porous surface into which ions, fine charged particles, and very fine particles may become attached. Errors may occur in your first sample due to these trapped trace elements. • ...

  • Seasonal movement of trace-element discharge in a typical south-Indian suburban community

    Four conventional activated sludge sewage treatment plants (STPs) in Southern India were chosen to investigate the occurrence of major ions and trace metals in dissolved fraction of the wastewater. Samples were collected from inlet and outlet of STPs during the pre-monsoon and monsoon seasons. Except for a few elements (Mn, Mo and Ni), the concentrations of the rest increased at the outlet of ...

  • XRF analysis for steel production | Spectroscopy Solutions

    Steel production is a highly technical process which requires careful control of the alloy constituents to achieve the best mechanical properties. Part of the steel making process involves the removal of slag. Slag is the remains of the smelted ore generated by high temperature metallurgical activity. Ores (e.g., Iron, copper, lead, and nickel) generally have unwanted minerals associated with ...

  • Environmental testing with XRF | Spectroscopy Solutions

    Monitoring of inorganic environmental pollutants is an ongoing challenge for analytical chemists. To establish the quality of different compartments of our environment (atmosphere, indoor air, water basins, soil, biota) in general a relatively large number of samples must be taken from a given location over the entire duration of sampling.29,30,31 ...

  • A soil column study to evaluate treatment of trace elements from saline industrial wastewater

    Industrial wastewater from the flue gas desulfurization (FGD) process is characterized by the presence of trace elements of concern, such as selenium (Se) and boron (B) and relatively high salinity. To simulate treatment that FGD wastewater undergoes during transport through soils in subsurface treatment systems, a column study (140-d duration) was conducted with native Kansas soil and saline ...

  • What is XRF? | Spectroscopy Guides

    X-ray Fluorescence (XRF) is a technique widely used in elemental analysis. It is based on the principle that an atom's inner electrons, when bombarded with high energy radiation such as X-rays, are ejected. The atom relaxes by emitting photons of characteristic wavelengths, which are used to identify the element.  If diagrams do not animate, try ...

  • Application of leaching tests on phosphogypsum by infiltration-percolation

    The phosphoric acid production obtained by attacking phosphate rock by sulphuric acid cogenerates considerable quantities of phosphogypsum. The world cogeneration is estimated about 100–280 Mt per year. In another context of sustainable development, the phosphate chemical industry develops different ways of phosphogypsum valorization, which makes its storage stack in a suitable way for its ...
