关于各种物料中钇、镱、镧、铈光谱定量测定资料比较丰富。但是,系统地研究各种载体作用下稀土元素的蒸发与激发机制,还是近几年的事,有相当一批文献发表。在此基础上,作者研究出一种简便的直接光谱法,测定矿物,岩石,水系沉积物中的钇、镱、镧、铈,以便在某些范围内取代繁见的化学光谱法。
On a variety of materials yttrium, ytterbium, lanthanum, cerium quantitative determination of the spectrum is rich. However, systematically studying the mechanism of evaporation and excitation of rare earth elements under various kinds of carriers, there are quite a number of documents published in recent years. On this basis, the authors developed a simple direct spectroscopic method for the determination of yttrium, ytterbium, lanthanum and cerium in minerals, rocks and sediments of water to replace the most common chemical spectroscopy in some areas.
