Three new salen derivative ligands (L1, L2 and L3), containing mixed-ligand donor sets of NSNO, have been synthesized. The thermodynamics of complexation reaction between new synthesized salens and copper(II) ion in acetonitrile solution was studied by conductometric method. Formation constants of the resulting 1:1 complex was determined from the conductance-moleratio data. The results have shown that the new salens, as a neutral chelating agent formed selective and stable complex with Cu(II) ion. Thus, the L1 new salen compound was used as neutral ion carrier in the construction of a Cu2+-PVC membrane electrode. The influence of some exper i mental parameters such as membrane composition, nature and amount of plasticizer, additive and concentration of internal solution on the potential response of the Cu2+-sensor were investigated. The electrode exhibits a Nernstian response for Cu2+-over wide concentration range (5.0×10-6-1.0×10-1 M) with a slope 29.7š0.5 mV/decade and detection limit 1.0×10-6 M. It could be used in a pH range of 4.0-8.0. The electroe shows excellent discriminating ability to wards Cu2+ ion with regard to several alkaliand alkaline earth metal ions. It has a fast response time of about 20 s. The proposed sensor as an indicator electrode was used success fully in the potentiometric titra tion of Cu2+-ions with EDTA.
