DETERMINATION OF RARE EARTH ELEMENTS IN GEOLOGICAL STANDARD ROCK SAMPLES BY INDUCTIVELY COUPLED PLASMA ATOMIC EMISSION SPECTROMETRY
Rare earth elements in the standard rock samples such as GSJ JG-1, GSJ JB-1, and USGS AGV-1 have been determined simultaneously by inductively coupled plasma atomic emission spectrometry. It has been found that heavy rare earth elements in JG-1 provide lower values when it is dissolved by the acid digestion method.
