Studies on the Atomization Mechanism of Sanmarium on the Graphite Probe Surface in the Graphite Furnace

Abstract

Abstract: In this paper, atomization mechanism of Sm(NO₃)₃ and Sm₂O₃ on the graphite probe surface in the graphite furnace was investigated experimentally using X-ray diffraction spectrometry.X-ray photoelectron spectroscopy and Auger electron spectroscopy.It showed that in the course of atomization, the samarium samples firstly decomposed into Sm₂O₃ then converted into SmOand samarium carbide, the atomization of samarium originated from the thermal decomposition of SmO, the formation of refractory carbide accounted for the severe memory effect of determination.
