| Abstract: | A method of inductively coupled plasma mass spectrometry(ICP-MS)was established to determine the trace elements in plant samples,such as vegetables,fruit and rice.After digested by the method of microwave digestion with HNO3-H2O2,six trace elements of Cd,Pb,Cr,Cu,Ni and Zn in the samples were analyzed,and the matrix interference were eliminated by Rh.The results indicated:the limits of detection(LOD)were in the range of 0.002—0.5μg/g with RSD of 0.84%—7.4%.The established method was used to determine the ten certified referenoe materials of rice flour(GBW10010),wheat(GBW10011),celery(GBW10048),scallion(GBW10049),and the analysis results were all in material reference range.The method was simple,rapid and accurate,and was suitable for the determination of multi-elements in agricultural samples simultaneously. |
