Simulteneous Determination of 15 Trace REE in Rocks by Emission spectrometry |
| |
| Abstract: | The method is based on the separation of REE from the accompanied
elements Fe, Al. Ca, Mg, Ba etc. by cation exchange resin. Then REE is coll-
ected on cation exchange paper from hydrochloride medium at pH 1-2. Af-
ter asking and ignition the residue is subjected to emission spectroscopic
determination. The results of GSD reference samples and Canadian reference
samples obtaind by this method and the certified values of these samples are
listed for comparison. |
