摘要

合成的聚苯胺-氧化石墨烯具有八面体结构，具有螯合配体EDTA（聚苯胺-氧化石墨烯-EDTA）的功能，可以在特定ph下捕获重金属离子，并应用于铅（II）离子的检测。采用差分脉冲溶出伏安法（DPSV）在不同的实验条件下进行检测。在本研究中，对材料进行了重复性、再现性和在另一pH值（Pb离子为4.5）下重金属离子的检测。对这些结果进行了详细的讨论，这表明，与以往报道的数据相比，本工作具有更高的灵敏度、选择性和可重复性。

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

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.
