镥是稀土元素中较有用,并且最昂贵的元素之一。我们研究了测定99.99％高纯氧化镥中14种稀土杂质的方法。实验部分试剂:氧化镥纯度为99.995％以上,其它14种稀土氧化物纯度均为99.95％以上,850℃在马福炉中灼烧之后,配成酸度为5％盐酸稀土标准溶液。仪器及工作条件:美国HFL-5000D型射频发生器,40.68MHz。民主德国PGS-2型两米平面光栅摄谱仪,光栅刻线651条/mm,用一级光谱。用改装的Goulden和Anthony的加热去溶装置,加热温度300℃。
镥 is one of the more useful and expensive elements of rare earths. We studied the method of determination of 14 kinds of rare earth impurities in 99.99% high purity oxide. Experimental Reagents: 氧 purity of over 99.995%,, other 14 rare earth oxides were more than 99.95% purity, 850 ℃ in the muffle furnace after burning, dubbed the acidity of 5% rare earth hydrochloric acid standard solution. Equipment and working conditions: the United States HFL-5000D RF generator, 40.68MHz. Democracy Germany PGS-2 two-meter plane grating spectrograph grating grating line 651 / mm, with a spectrum. The unit was degassed with modified Goulden and Anthony heating at 300 ° C.
