Determination of Boron in NdFeB Alloy by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES)

Abstract

The alkali melting method was used to pretreat the specimens of Neodymium-iron-boron alloy, and the inductively coupled plasma atomic emission spectrometer was used to determine the main element boron in NdFeB alloy. The parameters of the instrument were optimized to select the best spectral line for the determination of boron, and the effect of matrix effect was overcome by adding Fe. The method has good precision and accuracy, the recoveries are in the range of 99%∼101%, and the RSD are less than 1%, which is suitable for the determination of boron in daily production analysis.
