Fabrication and Characterization of Novel Pb(II) and Cr(III) Ion Selective and Sensitive Electrodes

Abstract

The Lead - Ion Selective Electrode (Pb-ISE) and Chromium-Ion electrode (Cr-ISE) is a method for the analytical determination of Pb(II) and Cr(III) in natural matrices. The ISEs are very sensitive, selective, and inexpensive analytical tools that can be applied to determine Pb(II) and Cr(III) in soil samples due to relatively high limits of detection. In the present work, we examined the possibility of using solid contact ISEs in soil analysis, combined with a simplified extraction method based on dilute HNO3 that can be carried out at the field site. The Ionic strength of lead and Chromium is measured by using The Pb-ISE and Cr-ISE were fabricated and their characteristics were studied separately and the Ionic strength of Pb(II) and Cr(III) was measured by using them, the results were found to be quite satisfactory.
