SPECTROGRAPHIC DETERMINATION OF ERBIUM
Technical Report
·
OSTI ID:4214362
With the lines and comparisons given, it should be possible to estimate erbium visually provided it is concentrated by the normal rare earth concentration procedure. With a limit reading of < 0.003% with respect to flux of erbium it is possible to achieve a limit of detection of < 0.01 ppm on the normal quantity (20 g) of uranium taken Interferences with other rare earths lines by erbium lines are such that at least for the present it is undesirable for erbium to be incorporated into the standard plates of either mixture I(Ce, Eu, Gd, Tb, Ho, Yb, and Lu) or mixture II (Nd, Pr, Sm, La, Sc, Yt, and Dy). Thus the lines at present in use for Ho and Yb in Mixture I and Dy, Pr, and Nd in mixture II would be interfered with. (auth)
