Direct spectrographic determination of residual rare earth in steel has been generallyregarded as impossible since the complex spectra of the major components of ten prevented the identi-fication and measurement of the weak rare earth lines. In this work the chemico-spectrochemical method is employed. The mercury cathode separ-ation and the ether extraction technique were used for the concentration of R. E. proceeding thespectrographic procedure. Yttrium or thorium is used as carrier and internal standard. The concentrated sample solution is droped on the tip of spectra pure carbon electrodes. A.C. arc (-1)is used to excite the spectra. This method permits the determination of as little as 50 γ of total rare earths in 1 gram sampleof steel with an error of±10％. 收稿日期: 1959-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李诗(钅卓) 王玉梅 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1959/V4/I1/81 [1] E.
