Determination of tungsten, silicon and aluminum in ammonium molybdate products by ICP-AES

       

  The development of inductively coupled plasma atomic emission spectrometry (ICP-AES) analysis technology has enabled the simultaneous, multi-element determination to be accurate, simple and fast and has rapidly developed abroad as a widely used and commonly used analytical method. Compared with analytical techniques, this method shows a strong competitive edge.

  Molybdenum ammonium molybdenum samples are multivalent elements, the emission line complexity, matrix interference serious. In this paper, the accuracy of experimental calibration with appropriate sample preparation, computer background subtraction, matrix blank matching and so on was used to give full play to the advantages of simultaneous determination of multiple elements in ICP-ACE spectroscopy. Three elements at the same time determination.
