Abstract:
Objective To determine the content of six heavy metal elements of arsenicum(As),mercury(Hg),cuprum(Cu),plumbum(Pb),cadmium(Cd) and chromium(Cr) in Rhizoma Curcumae Longae.Methods Samples were digested with microwave digestion system,and the contents of Cu,Pb,Cd and Cr were determined by graphite furnace atomic absorption spectrometry(GFAAS);the contents of As and Hg were determined by atomic fluorescence spectrometry(AFS),and the reproducibility and recovery of the method were also examined.Results As and Hg contents in most of the products were below the limit.Only Cu,Pb and Cd contents exceed the limit.The recovery was 86.3 %～113.4 %and RSD was 10.4 %.Conclusions The method is simple and accurate,and can be used for the determination of heavy metal in Chinese herbs.
