title: Determination of neodymium and boron in iron-neodymium-boron alloys by direct-current plasma atomic-emission spectrometry.
abstract: Rapid, accurate methods for the determination of neodymium and boron in iron-neodymium-boron alloys are presented. The procedure involves dissolution of the alloy with nitric acid and measurement of the elemental concentrations by direct-current plasma atomic-emission spectrometry. Lithium is added in the determination of neodymium, to control interferences. The relative standard deviations are approximately 1%, and the accuracies comparable to those obtained by classical chemical methods.
