| Abstract: | Objective: To establish a method for simultaneously determining fifteen element contents(Mo,Co,Se,Si,Mn,Cu,Sn,Ba,Fe,P,Zn,K,Na,Mg and Ca) in six Mongolian drug.Methods: Microwave digestion procedure was applied with HNO3-H202(5∶ 1v/v) mixed acid for digesting Mongolian drug.Element concentrations were determined by ICP-AES.Results: The results showed that the average recoveries all analytical elements were from 96.4% to 104.5% with RSD below 5% under optimum experiment condition.Conclusion: The method is simple,rapid and accurate,and suitable for simultaneous determination of above-mentioned 15 elements in Mongolian drug. |
