  • Title: Determination of zinc, copper, lead and cadmium in some medicinally important leaves by differential pulse anodic stripping analysis.
    Author: Jyothi NV, Mouli PC, Reddy SR.

    Abstract:
    Levels of zinc, copper, lead and cadmium have been determined in some medicinally important leaves by differential pulse anodic stripping voltammetry (DPASV). High pressure digestion with nitric acid (HPA) was used for sample digestion. The accuracy of the method was verified by the parallel analysis of leaves with inductively coupled plasma atomic emission spectroscopy (ICP-AES) and recovery studies by the analysis of standard reference materials. Based on elemental levels the utility of these leaves in medicine are discussed. Statistical treatment has been used in order to understand the correlation between elements in these leaves.
