A high-performance electrochemical sensor for the determination of Pb(II) based on conductive dopamine polymer doped polypyrrole hydrogel

[Display omitted] •A kind of hydrogel based on dopamine polymer doped polypyrrole (PDA-PPy) was synthesized in rapid one-pot method.•PDA-PPy hydrogel exhibited selective adsorption capacity for Pb(II).•PDA-PPy/SPCE showed good sensing performance for Pb(II) detection. Lead is one of the most common...
