Type: article
Abstract: The present paper, outline the simultaneous determination of lead and zinc using electrochemicalnanosensors like electrochemical conjugated polymers (ECP’s) which is prepared by polymerizationprocess and its application in biological samples. In this work the metal ions were complexed with anewly sysnthesised analytical reagent 4-(2-hydroxy phenyl ethaminodiol), benzene-1, 3-diol (4-2-HPEDB-1,3,D) and analysis was carried out by anodic stripping voltammetry. Electrochemicalcharacteristics like scan rate, deposition potential, deposition time, effect of pH were studied underoptimized conditions. The calibration curve was constructed with in the range of 0.05–200 µg mL-1 atpH 4.0 (acetate buffer) having correlation factor as 0.9964 for lead, 0.9992 for zinc and RSD willfound to be 5.3 %. The study of interfering ions during the analysis of lead and zinc with the error of>2%, shows the sensitivity and selectivity of the proposed method. The accuracy and precision of theproposed method was checked by the analysis of Certified Reference Material (CRM) and results werepertained in this paper.
