| Abstract: | Neodymium and dysprosium were determined by inductively coupled plasma mass spectrometry （ICP- MS）. 187Re was used as an internal standard to correct the signal shift of instrument. The concentrations of Nd and Dy were linear with the intensity of signal, and the linear correlations coefficients（r2） were 0.999 8 and 0.999 7, the detection limits were 0.02 ng / mL and 0.006 ng / mL, the average recoveries were 99.5% and 97.4%, RSD were 3.5% and 4.3%, respectively. |
