Abstract:

An automated borate fusion procedure was investigated as a sample preparation method, after removal of organic matter, for the analysis of seven elements in NBS Standard Reference Material 1571 Orchard Leaves by energy-dispersive x-ray spectrometry. A 2.0 g sample was pretreated by oxidation with H₂SO₄—HNO₃ acid mixture and the residue was fused with 6.5 g of lithium tetraborate in the conventional manner. Relative errors on the order of 2 to 10% were obtained for K, Ca, Fe, Mn, Zn, and Pb.
