| Abstract: | Objective To establish a method for the determination of 12 trace elements(Al,Mn,Fe,Ni,Cu,Zn,As,Se,Cd,Ba,Hg,Pb) in Radix Euphorbiae Ebracteolatae by inductively coupled plasma-mass spectrography(ICP-MS).Methods After microwave digestion,12 trace elements in the samples were determined by ICP-MS,and the method was validated.Results The calibrating curve of 12 trace elements showed good linear relationship,and the mean recovery met the analytical requirement.Conclusion This method is simple,accurate,and effective.It can be used for the research of Radix Euphorbiae Ebracteolatae Radix. |
