    Determination of Arsenic and Cadmium in Powdered Rice by Inductively Coupled Plasma-Mass Spectrometry and Evaluation of the Uncertainty

    • The microwave digest technique combined with inductively coupled plasma-mass spectrometry (ICP-MS) was used for the determination of arsenic and cadmium in powdered rice. The measurement uncertainty was evaluated by establishing a mathematical model. The measurement results of arsenic and cadmium in powdered rice were (0.182±0.012) mg/kg and (0.262±0.016) mg/kg, respectively, with the coverage probability of 95%. The major uncertainty components were from standard curve fitting and test solution measurement. The research method can be used for measurement of harmful elements in powdered rice by ICP-MS.
