| Abstract: | To establish a method for rapid digestion and simultaneous detection of rare earth elements in Maca.Rare earth elements in Maca were digested by microwave digestion system and determined by ICP-MS.In was used as the internal standard.The correlative coefficient of the calibration curves was over 0.9990,the recovery factor was from 91.0%~111.0% and the relative standard was from 0.4%~3.7% for all the analyzed elements.The method was simple,rapid,accurate and highly sensitive.The rare earth elements in Maca can by simultaneously determined by ICP-MS. |
