[Determination of metal elements in Mongolian medicine Chagederi by ICP-AES with microwave digestion].
In the study of the Mongolian medicine we found that the Mongolian medicine contains a great amount of trace elements and nutrition composition of amino acids etc, in which trace elements that human body needed are fairly rich but the heavy metals are very little. A method for the determination of Ca, Mg, Al, Fe, Mn, Sr, Cu, Zn and Pb in Mongolian medicine Chagederi (1# and 2#) by ICP-AES with microwave digestion was studied. The recoveries of standard addition are in the range of 97.5%-105.5%. The relative standard deviation is < or = 2.88, and the detection limit is in the range of < or = 0.009 microg x L(-1). The results show that 1# and 2# have some differences and the medicine property and drug effect has some relation with trace elements.
