Abstract
Abstract Various mineral acids are compared in measuring metals in plant materials by flame and flameless atomic absorption spectrometry. NBS-SRM 1571, Orchard Leaves, is utilized as the plant material. The combination of H2SO4 and HNO3 is found to be the most suitable for measuring Fe, Mn, Cu and Zn by flame atomic absorption spectroscopy, while HNO3 is found to be the best for measuring Cu, Mn, and Pb by flameless Atomic Absorption spectroscopy.
