title: [Determination of 15 trace rare earth elements in rice by microwave digestion ICP-MS].
abstract: An ICP-MS method for direct determination of 15 trace rare earth elements in rice was developed. Rapid and complete dissolution of rice was achieved by a microwave digestion procedure with concentrated nitric acid and hydrogen peroxide. The detection limits are 7.0-25.8 pg/mL, the recoveries for spiked samples are 95-105%, RSDs are 2.3-4.2%. This method is rapid, sensitive and accurate.
