A PVC membrane electrode for lead ions based on 4Π-vinylbenzo-15-crown-5 homopolymer as membrane carrier was prepared. The electrode exhibits a Nernstian response for Pb 2Ο© ions over a wide concentration range (4.0 Ο« 10 Οͺ3 to 1.0 Ο« 10 Οͺ6 M), with a limit of detection of 7.0 Ο« 10 Οͺ7 M. It has a respo
Liquid-liquid extractions of sodium and potassium picrates with naphtho-15-crown-5 (N15C5) into 1,2-dichloroethane are studied, in order to clarify the factors governing the high potassium ion selectivity of the N15C5-based membrane electrode. The distribution coefficient of N15C5 between water and
