Ethanol Sensor Using Two Chloride Ion-Selective Polymeric Membrane Electrodes.

Bicarbonate interference with chloride-ion-selective electrodes.

echocardiography. All attending phy-sicians/cardiologists were blinded to the BNP results. To determine the diagnostic accuracy of the two assays for CHF, we performed ROC plot analysis, and areas under the curve (AUC) were calculated for both BNP assays. Comparisons between AUC were assessed according to the method of Hanley and McNeil (10). Cutoff values for the two methods were determined at...

Theory and Computer Simulation of the Time-Dependent Selectivity Behavior of Polymeric Membrane Ion-Selective Electrodes.

A theoretical treatment of the time-dependent potential response of ion-selective electrodes to sample solutions containing primary and interfering ions is presented. The theory accounts for the influence of ion fluxes in the electrode membrane and the contacting aqueous sample layer and describes the variations in the apparent selectivity behavior as a function of the measuring time. The appli...

An Electrochemical Sensor Based on Novel Ion Imprinted Polymeric Nanoparticles for Selective Detection of Lead Ions

In this study, the novel surface ion-imprinted polymer (IIP) particles were prepared and applied as a electrode modifier in stripping voltammetric detection of lead(II) ion. A carbon paste electrode (CPE) modified with IIP nanoparticles and multi-walled carbon nanotubes (MWCNTs) was used for accumulation of toxic lead ions. Various factors that govern on electrochemical signals including carbon...

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...
