Application of ICP-AES to the Detection of Heavy Metals in Cordyceps militaris from Shenyang

Abstract:

The microwave digestion-ICP-AES was used to detect the Cr, Cd, Pb, As, Hg and Ni in cordycepsmilitaris from Shenyang. The method accuracy was proved by the national standard method. The result shows the sequence of heavy metals was Pb>Ni >As > Cd> Cr, and Hg was not detected, as was detected in few sample. All the data showed that cordycepsmilitaris accords with the national standards. The method average recovery is 94.07%-107.58%, and RSD is 0.84%-3.25%. It is a promising analysis method on detection of heavy metals in cordycepsmilitaris.
