in order to study the cu(ii) ion selective electrode, an optimized membrane was prepared by mixing of 30 mg of pvc powdered, 5 mg of considered ionophore, 60 mg of plasticizer and 5 mg of additive. the sensor showed a near nernstian response for cu(ii) ions over a concentration range from 1.0×0-6 –1.0×0-2 m with a slope of 28.90.5 mv per concentration decade with a working ph range of 3.5-6.3. ...

Here, a simple, quick, Low cost and sensitive Potentiometric method is described for tramadol hydrochloride measurement using .PVC membrane electrode based on neutral ligand (E)-N'-(1-(2-hydroxyphenyl)ethylidene)benzohydrazid. Besides, effect of various parameters like ionic additives, membrane solvent and pH on the Potentiometric response of the electrode are investigated. The best electrode p...

Clomipramine hydrochloride, active component of an antidepressant drug, was determined in the pharmaceutical formulation by two kinds of potentiometric sensor; a PVC membrane sensor and a carbon paste electrode modified by MWCNTs and ionic liquid. Both sensors were corporated with clomipramine-tetraphenylborate ion-pair complex and they respond based on ion exchange mechanism. The best PVC memb...

A PVC-based membrane containing cerium phosphate was developed. Unlike the cerium phosphate itself that acts as a cation exchanger, the membrane exhibited anion-exchange properties. Therefore, the utility of this compound as a sensory element for detection of molybdate ions was pursued. The response of molybdate selective electrode based on this membrane was perfectly linear in the concentr...
