  • Title: PIXE as a complement to ICP-OES trace metal analysis in Sudanese medicinal plants.
    Author: Mubark Ebrahim A, Etayeb MA, Khalid H, Noun M, Roumie M, Michalke B.
    Journal: Appl Radiat Isot; 2014 Aug; 90():218-24. PubMed ID: 24814608.
    Abstract:
    This paper compares trace element concentrations (Ca, K, Sr, Fe, Mn, Zn, Ni, Cu, Co and Cr) in 27 Sudanese medical plants determined in parallel by PIXE and ICP-OES to get information on which technique is preferable at different matrices and element concentrations. PIXE correlates well to ICP-OES for Sr, Mn, Ca, K, Zn and Fe determinations. ICP-OES seems to be the superior technique over PIXE when measuring low concentrated elements (chromium, cobalt, nickel and copper) in the medicinal plants.
