钐钴永磁材料的应用日益普遍。目前生产控制分析是用铜铁试剂把钴分离后,EDTA容量法测定钐。本文讨论了钐钴等元素在空气——乙炔焰中的发射行为,少量铁、铝、钙、镁、锰、镧、铈、镨、铕、钆、钕的干扰情况,拟定了测定钐的火焰发射标准对比法。本文所谈的测量条件是:空气压力1.8 Kg/Cm~2,空气流量14升/分,乙炔流量
The application of samarium cobalt permanent magnet material is increasingly common. The current production control analysis is the use of copper and iron reagent to separate cobalt, EDTA volumetric method for the determination of samarium. In this paper, the emission behavior of samarium-cobalt and other elements in air-acetylene flame and the interference of a small amount of iron, aluminum, calcium, magnesium, manganese, lanthanum, cerium, praseodymium, europium, gadolinium and neodymium were discussed. Launch standard comparison method. In this paper, the measurement conditions are: air pressure 1.8 Kg / Cm ~ 2, the air flow 14 liters / min, acetylene flow
