Atomic Absorption Spectrometric Determination of Microamounts of Heavy Metals in Plant Leaves
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.
