Mechanism of Pb(II) double peaks

Interfacial kinetics reveals interference source

This work integrates voltammetric signals and interfacial simulations to reveal that Pb(II) double peaks in Pb(II)-Cu(II) systems originate from parallel deposition on Cu deposits, providing new insights for electroanalysis reliability.

Advantages

The existence of the second peak was controlled through the adjustment of experimental conditions.

Simulations based on the model were combined with experiments to illustrate that double peaks of Pb(II) were caused by the parallel deposition on Cu(II) deposits.
