摘要

•Pyrrole-1-carboxylic acid (Py-CO2) was synthesized and applied for modification of pencil graphite electrodes (PGE).•Electropolymerization of Py-CO2 created a sensing film for selective metal extraction and determination.•The modified electrode, PPy-CO2@PGE, provided excellent sensitivity and selectivity for detection of Pb2+ and Cd2+.•Accurate analysis of Pb2+ and Cd2+ in several natural water sources was demonstrated and independently verified.
