PIXE as a complement to ICP-OES trace metal analysis in Sudanese medicinal plants

Appl Radiat Isot. 2014 Aug:90:218-24. doi: 10.1016/j.apradiso.2014.04.013. Epub 2014 Apr 19.

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.

Keywords: ICP-OES; Medicinal plants; PIXE; Trace elements.
