| Abstract: | The contents of 12 trace elements in pickpurse and maror have been determined by atomic absorption spectrometry.The sample can be dissolved by ashing method.The mixed standard solution of the elements was prepared The contents of nutritious and poisonous elements in pickpurse and maror were compared,and the cause which the contents of Pb and Cd in the samples exceeds standard was discussed. |
