摘要: Abstract We present a route toward the ultra-sensitive and -selective sensing Pb2 + by stripping voltammetry beyond selective adsorption of polypyrrole-reduced graphene oxide (PPy-RGO) nanocomposite Hg2 +. Electrochemical experiments have shown that could be reliably measured at very low levels (Sensitivity: 0.642 μA nM− 1; LOD: 4 pM) on PPy-RGO modified electrode in presence
