reliably measure various analytes in clinical, industrial and environmental samples. Due to
the toxic nature of lead (II) it is important to monitor Pb 2+ distribution in natural waters. This
may be achieved by implementation of ion-selective electrodes (ISEs) with high selectivity
towards lead (II) and low detection limit. A great number of Pb 2+-ionophores were
synthesized and studied. In this work lead (II)-selective ionophores, starting from late 90s …
