【Abstract】 In this work extractive chromatographic method is used for the separation of REE with P507-containing resin as stationary phase, and hydrochloric acid as mobile phase. The ICP spectrometry is used for determinations. A cyclone spray chamber is used, instead of conventional Scott-type chamber. The detection limits of REE are reduced to a half or one order of magnitude. A simple method has been proposed which can simultaneously determine 15 REE in minerals with accurate results.更多还原
