Selective and sensitive detection of Pb (II) from aqueous solutions at optimized pH and analyzed for repeatability and reproducibility

Abstract

Present communication holds synthesized PANI-GO functionalized with EDTA (chelating ligand) (PANI-GO-EDTA) which possess octahedral geometry to catch up the heavy metal ions at specific pH. The synthesized composites were applied for detection of Pb (II) ions. The detection was carried out under different experimental conditions using differential pulse stripping voltammtry (DPSV). In this study the materials are studied to assess the repeatability, reproducibility and detection of heavy metal ions at another pH which was 4.5 for Pb ion. These results were discussed in detail which reflects that, present work holds superior sensitivity, selectivity, repeatability compare with earlier reported data.
