PROCEDURES FOR THE DETERMINATION OF TRACE ELEMENTS IN MILK BY ENERGY DISPERSIVE X-RAY FLUORESCENCE SPECTROPHOTOMETRY

摘要

A procedure for the simultaneous determination of K, Ca, Fe, Cu, Zn, Br, Rb, Sr, and Pb in milk by x-ray fluorescence spectrometry is described.nComparison of molybdenum-tube excitation and cadmium-109 isotopic excitation is discussed, and results of over 500 milk samples are summarized.
