Introduction

Neodymium (Nd) that is one of the rare earth elements belonging to the lanthanoid is used as a raw material for strong permanent magnets, lasers, optical glass, and special rubber in various industries. There is not much known information about Nd analysis using atomic absorption spectroscopy (AAS), because recently inductively coupled plasma atomic emission spectroscopy (ICP-AES) is mainly used to analyze trace rare earth elements. According to known references, Nd can be analyzed at hundreds of ppm levels using AAS. In 1973, Hiroshi Sunahara (Japan) conducted a study using AAS to analyze Nd, Eu, Gd, and Er under different conditions of inorganic acids, measurement methods, and interfering substances, which also showed a similar level of analytical sensitivity. However, since conventional instrument such as AAS are also improving their performance little by little, it is necessary to reconfirm the dynamic range and analytical conditions in the device of the recent specification. This application news confirm the sensitivity and dynamic range to analyze Nd using AAS, and introduce the optimized conditions for quantitative analysis of trace Nd. The optimized analytical conditions using the AA-7000 model (Shimadzu Co., Ltd., Japan) were determined while changing several factors affecting absorbance of Nd.
