A new pendant‐arm derivative of diaza‐18‐crown‐6, containing two oxime donor groups, has been synthesized and incorporated into a polyvinyl chloride (PVC) membrane ion‐selective electrode. The electrode shows selectivity for Ag + ion, with a near Nernstian response. Pb 2+ , Cu 2+ , Hg 2+ , and Tl + are major interfering ions, with Cd 2+ having minor interference. The electrode shows no potentiometric response for the ions Mg 2+ , Al 3+ , K + , Ca 2+ , Ni 2+ , Fe 3+ , and La 3+ , and is responsive to H + at pH<6.
