An investigation by using ion-selective electrodes on the discrimination of Pb2+ and R3Pb+, where R is an alkyl substituent, is the subject of the present paper. Selective macrocyclic thiacrown ethers are applied as active ligands. The response and selectivity of electrodes based on thiacrown ethers and ionophore-free electrodes towards inorgnaic lead ions and alkyllead substituents in model solutions and mazine cell sap are reported. The presented electrodes could be recommended as a relatively cheap and simple method for lead speciation.
