| Abstract: | Employing a high detection sensitivity,high-purity germanium detector and microcomputer multi-channel energy spectrometry based on the principle of energy dispersive X-ray fluorescence (EDXRF), the K-shell XRF energy spectrum of rare earth elements excited by radioisotope are obtained directly. The contents of 15 rare earth elements in extraction process are calculated by the method of energy spectrum analysis. The larger analysis ranges and smaller relative errors make the analysis system generally suitable the demands of on-line analysis in extraction process. |
