摘　　要：本文对比分析了测定稀土总量的复合酸溶-电感耦合等离子体光谱法、草酸盐分离-重量法和阳离子交换树脂分离-偶氮胂Ⅲ光度法,结果表明:较其它两种方法,复合酸溶-电感耦合等离子体光谱法优点在于精确度高、效率高、速度快、前处理简单。Rapid determination of total amount of 15 rare earth elements by compound acid dissolution-Inductively Cou⁃pled Plasma Spectroscopy was established in this article.The advantages of the method are high accuracy,rapidity,and sim⁃ple pretreatment,compared to oxalate separation gravimetric method and cation exchange resin-arsenazoⅢspectrophotom⁃etry.
