Abstract

Leaf-sample was digested with conc.HNO3 and HClO4.The elements with high contents(Cu,Zn and Mn) were determined by FAAS,while those with low contents(Pb,Cd and Cr) were determined by GF-AAS.To eliminate the matrix interference and interferences of some co-existing elements,standard addition method was used in the determination of Lead and cadmium.
