[Objective] To develop a method of determining trace lead and chromium in Sinocrassulaindica var. Luteorubra through graphite furnace atomic absorption. [Method] Using ammoniumdi hydrogen phosphate as matrix modifier to determine lead and chromium contents in Sinocrassulaindica var. Luteorubra under the given working conditions of instrument. [Results] The lead was in the linear range of 0-100 μg/L(r=0.999 1) and the chromium in the range of 0-30 μg/L(r=0.998 9). The detection limit was 0.157 μg/L with lead and 0.336 μg/L with chromium. The precision was in the range of 10.07%-11.54%, and the recovery was in the range of 81.6%-92.4%. Lead and chromium contents in flower and lead content in leaves were lower than the set limits on food contaminants (Pb<5 mg/ kg, Cr<2 mg/kg)，but lead and chromium contents in stems and chromium content in leaves exceeded the values set by the government. Lead content in Sinocrassulaindica var. Luteorubra followed a order of stem>flower>leaf, and chromium content followed a order of stem>leaf>flower. [Conclusion] The method can be used for the determination of trace lead and chromium in Sinocrassulaindica var. Luteorubra with high sensitivity, low detection limit, and high precision.
