| Abstract: | Direct determination of the contents of 19 major or trace elements:K,Na,Ca,Mg,Si,Al,Fe,P,Sr,Ti,Mn,Zn,Pb,B,Ba,Cu,Li,V and Ni in plant samples by ICP AES are reported in this paper.The solution of plant standard sample GBW07603 was prepared by five pretreatment methods:dry ashing,HNO 3+H 2SO 4+HClO 4,H 2SO 4+H 2O 2,HNO 3+H 2SO 4+HClO 4+HF and ashing+NaOH method.Suitable pretreatment methods were found for the determination of the elements by comparing standard deviations and relative errors of the results,thus providing a scientific basis for the selection of suitable pretreatment of chemical element analysis in plants. |
