| Abstract: | Using hydrofluoric acid and nitric acid as digestion solvent, the rutile ore sample was pretreated by optimizing the microwave digestion procedure, 15 trace rare earth elements in the rutile ore were determined by inductively coupled plasma-mass spectrometry. The results show that correlation coefficient of the method is in the range of 0.999 1~1.000 0, precision RSD%is lower than 7.36%, recoveries are in the range of 92.3%~106.9%. This method has wide linear range, high speed, low detection limit, high accuracy and precision, so it can be used to test the rare earth elements in the rutile ore. |
