| Abstract: | Objectives To detect the concentrations of neodymium oxide in the air of electrolysis workshops of the rare earth enterprises.Methods By means of the membrane digested by nitric acid,the concentration of neodymium and its compounds in the workshopwas were determined by inductively coupled plasma mass spectrometry.Results In the range of 0~50 ng/mL,the liner regression correlation coefficient was 0.9998,detection limit was 0.0019 μg/mL,the relative standard deviation was 2.1%~3.3% and the recovery was 99%~104%.Conclusion The method is sensitive and stable,and has low detected limit. |
