Objective: The primary speciation of ten kinds of trace elements in mongolian medicine Argari- 35 was investigated. Methods: The primary speciation of various kinds of trace elements in samples were measured and the primary speciation analysis parameters were calculated. Results: The highest content was Mg( 465. 51 μg/g) and the lowest content Ti( 13. 19 μg/g). The highest total extraction rate was Mg( 83. 00%). The lowest total extraction rate was Ti( 11. 94%). The contents of Cd,As,Hg and Pb were very low...
