A spectrochemical method was developed for determining rare earth elements in artificial mixtures conforming to the mean chemical composition of the sum of the rare earth oxides or of the cerium group. This method is based on the three-stage method. Zirconium is employed as an internal standard. Photographs are taken on a high dispersion spectrograph. A direct current arc serves as the excitation source. The determination limits are Y--0.01 to 3%, Nd-- 0.3 to 3%, La--0.1 to 3%, Sm--0.1 to 3%, Dy--0.1 to 3%, Gd--0.03 to 3%, Eu--0.03 to 3%, Er--0.01 to 1%, and Yb--0.01% to 1.0%. The error is within limits of plus or minus 12%. (auth)
