Determination of the Harmful Elements in Rice and Rice Flour Noodles by Inductively Coupled Plasma Mass Spectrometry

Abstract:

In this study,a method was developed for the determination of Pb,As,Cr,Cd and Sb in the Rice and Rice Flour Noodles by inductively coupled plasma-mass spectrometry(ICP-MS).Calibration with Ge,In,Bi,Sc,as the internal standard was used.The samples were digested using amicrowave oven.The results of the analysis of reference material were compared with certified values.For all analyte elements,the correlation coefficient of the calibration curves were higher than 0.9990,there coveries at the range of 81.3% ~99.2% range,the relative standard at the range of 1.35%~3.16% range(n=6).
