title: [Determination of trace elements in Mongolian medicine gardi-13 by ICP-AES with microware digestion].
abstract: In the study of Mongolian medicine the authors found that the Mongolian medicine contains large amount trace elements, and is particularly rich in human-body-needed trace elements, but heavy metals are very little. A method for the determination of Ca, Cu, Zn, Fe, Mg, Mn and Pb in Mongolian medicine gardi-13(1#, 2#, 3#) 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 = 2.90, and the detection limit is smaller than < or = 0.009 microg x L(-1). The results show that 1#, 2# and 3# are some different, and the smell and function have some relation with trace elements. The authors can control the accuracy of preparation dosage and guarantee the quality of products by determining the trace elements.
