title: [Study on primary speciation of seven metallic elements in pearl powder].
abstract: We have determined seven metallic elements in various extract of pearl powder by FAAS. The result implies that the quantity of different element in water and acidic solvent system is different. It has supplied reference data for the further studies of speciation of metallic elements in natural product also.
