A siloxane-crown ether polyamide copolymer (PDMS-PA-DB18C6) was electrochemically investigated for fabrication of lead-sensitive electrodes for trace analysis in aqueous solutions. The PDMS-PA-DB18C6 electrodes were successfully evaluated for anodic stripping voltammetric determination of lead(II) as a promising alternative for the detection of lead at ppb levels. By a judicious choice of the deposition time, electrolyte concentration and pulse amplitude, good analytical performance of the developed sensor could be achieved, with a linear response in the range of 20–700 ppb, when LOD of 3.5 ppb could be attained. This method showed a good degree of selectivity and sensitivity for lead, suitable for the determination of Pb2+ in wastewater sample.
