Preparation of electrochemical sensor for lead(II) based on molecularly imprinted film

► A high selective voltammetric sensor for lead(II) is prepared. ► Using schiff-base as assembling monomer of imprinted membrane is a new try. ► The stability and the life of imprinted membrane are improved by storing into lead ion solution. ► The redox process of lead ion on the imprinted electrode is controlled by surface reaction.
