Ion selective electrodes using Urushi as a matrix of the membrane

Selective Membrane Electrode for Bromide Ion Based on Aza Pyrilium Ion Derivative as a new Ionophore.

A highly selective electrode for Bromide ion based on aza pyrilium derivative as an excellentionophore is described.The sensor exhibits a good linear response with a slope of ( 60±1 ) mV per decadeover the concentration range of ( 1×10-3 – 9×10-6 M ) , and a detection limit of ( 3×10-6 M ) of Bromideions .The electrode response is independent of pH in the range of(4.0 –9.5).Selectivity coeffici...

Mechanistic Aspects of Ion-selective Membrane Electrodes. a Subjective View

Progress in the field of ion-selective membrane electrodes is viewed in terms of a dynamic interplay between advances in mechanistic understanding and the development of practical electrodes. Techniques used for the elucidation of glass, liquid, and crystal membrane electrode operation are discussed and possible mechanisms are considered. Scientific progress is limited not only by the rate of g...

Fe (II) Ion-Selective Membrane Electrode based onTetra-Phenyl Porphyrin in PVC Matrix

Fe2+ ion-selective membrane sensor has been fabricated from polyvinyl chloride (PVC) matrixmembrane containing neutral carrier tetra phenyl porphyrin (TPP) ionophore. The addition ofsodium tetraphenylborate (NaTPB) and the plasticizer DBP has been found to substantiallyimprove the performance of the sensor. The best performance was obtained with the sensor havinga membrane of composition of TPP...
