A new polyvinyl chloride (PVC) membrane electrode that is highly selective to Fe(II) ions was prepared using N-phenylaza-15-crown-5 (NPA15C5) as a suitable neutral carrier. The sensor exhibits a Nernstian response for Fe(II) ions over a wide concentration range (1.0 Â 10À2 to 1.0 Â 10À6 M) with a sl
