In this research, a coated graphite electrode was constructed for determination of Mg2+ in pharmaceutical supplements. The designed sensor demonstrates an ideal Nernstian slope (30.1 mV. Decade-1) over a wide concentration range (1×10-6- 1×10-1 Mol L-1). The selectivity of the sensor was evaluated over 16 different cations by matched potential method and no serious interference was observed fro...

Potentiometric sensor based on commercial pencil graphite electrodes coated with polyaniline (PAni) composite with Eosin Y (EY) termed as PGE/PAni-EY have been developed for potentiometric determination of silver ion. The electrode exhibited linear response with Nernstian slope of 57.6±0.8 mV per decade within the range of 1.0×10 to 1.0×10 M with limit of detection 6.5×10 M silver ion. Fast and...

The aim of this study was to construct and characterize an ion selective electrode for the potentiometric determination of thorium ions. On hand study we introduced a new calixarene molecule p-tert-butyl-thiacalix[4]arene derivative as ionophore for thorium(IV) selective polymeric membrane electrode. Due to the decisive role of solvent mediators, we fabricated membranes with the plasticizers DB...

We assessed the magnitude of the errors in ionized-calcium measurements resulting from changes in electrolyte composition for three different ion-selective electrodes: the Orion Model 93-20, the Radiometer F2112, and the Simon neutral carrier membrane electrode. We attempted to distinguish between errors arising from changes in calcium ion activity and those due to interferences in the electrod...

Ion-selective electrodes have been applied to analysis of blood electrolytes with some success. However, currently available ion-selective electrode systems tend to be elaborate and expensive. We describe a clinical electrolyte analyzer in which inexpensive ion-selective electrodes are used. The elec‘trodes are in the configuration of thin wires and are all solid in construction. They may be di...

A simple automated method for the estimation of ammonia in perchloric acid supernate of blood or plasma using an ion-selective electrode (Orion Ammonia-selective electrode, Model 95-10) is described. The reliability of the proposed method has been checked against an ion-exchange resin procedure, which has been chosen as a standard procedure. Regression equation and correlation coefficient for t...

Ion-Selective Biosensors In article 2202141, Sam Emaminejad and co-workers develop a touch-based noninvasive system to monitor lithium-based pharmacotherapy. It utilizes thin organohydrogel lithium ion-selective electrode (TOH-ISE) that has dehydration-resistant properties, minimizing signal drift, allowing for sweat collection. The is successfully validated on patient under therapy, demonstrat...

in this work we introduce a practical use of synthesized schiff base metal complex in sensing application. a new perchlorate-selective electrode based on the complex n, n'-4-nitro-phenylmethanebis-(salicylaldiminato) copper (ii) [cul] as the membrane carrier was developed. the electrode exhibits a good  nernstian slope of -55.0 ± 1.0 mv/decade and a linear range of  for perchlorate. the limit o...
