Abstract: Objecetive：To establish methods for determination of heavy metals including plumbum， cadmium， arsenic， mercury and cuprum in Testa arachis. Methods：Determinatin of plumbum， cadmium， and cuprum was conductedby atomic absorption spectrometry， Determination of arsenic was conducted by hydride generation system. Determination of mercury was conducted by Cold vapor absorption. And the methods were validated. Results：The results were reasonable and effective through the detection and methodological study of Pb， Cd， As， Hg and Cu. The linear correlation coefficients were greater than 0.995. The average recoveries were 84%、92%、82%、88%、81%.The heavy metal residues of 24 batches of sampleswere 0.00-1.23、0.00-0.07， 0.00-0.18， 0.00-0.08， 0.00-16.3 mg·kg-1， respectively. Conclusion：These methods in the research are simple， accuracy， reproducible and can be used to determine the five heavy metals in Testa arachis， and to provide more comprehensive quality control methods.
