Energy dispersive X-ray fluorescence method with chemical preconcentration has been worked out for Mn, Fe, Ni, Cu and Zn determination in plant materials. The analytical procedure involves wet digestion of organic matter, precipitation of metal ions with NaDDTC and the measurement of Kα emission lines of the elements to be determined. The overall precision of the method ranges from 3 to 7% /one relative S.D./ depending on the element.
