Cs+-selective solvent polymeric membrane-based ion-selective electrodes (ISEs) were developed by doping ethylene glycol-functionalized cross-linked polystyrene microspheres (P-EG) into a plasticized poly(vinyl chloride) (PVC) matrix containing sodium tetrakis-(3,5-bis(trifluoromethyl)phenyl) borate (TFPB) as the ion exchanger. A systematic study examining the effects of the membrane plasticizers bis(2-ethylhexyl) sebacate (DOS), 2-nitrophenyl octyl ether (NPOE), and 2-fluorophenyl nitrophenyl…

A Potentiometric Sensor Based on a Copper(II) Ion Composite for Vitamin C Determination in Urine
Abstract We developed an all-solid-state sensor for monoascorbate ion based on a composite containing copper(II) ions (5 wt %), graphite and epoxy resin. The sensor presented super-Nernstian response
Electrical Properties of Two Types of Membrane Component Used in Taste Sensors
In this study, two types of membrane electrodes are fabricated, based on PADE or TFPB, respectively, using 2-nitrophenyl octyl ether (NPOE) as a plasticizer and it is found that any concentration of PADE membranes always had low ion selectivity, while the ionSelectivity of T FPB membranes was concentration-dependent, showing increasing ion selectivities with the TFP B concentrations.

Pregabalin is a structural analogue of, but functionally unrelated to, the naturally occurring neurotransmitter -aminobutyric acid with potent analgesic, anticonvulsant and anxiolytic activity and it is very pertinent to determine pregabalin in a sensitive and selective manner.
Quantification of Pharmaceutical Bitterness Using a Membrane Electrode Based on a Hydrophobic Tetrakis [3,5-Bis (trifluoromethyl) phenyl] Borate
A membrane electrode based on hydrophobic tetrakis [3,5-bis (trifluoromethyl) phenyl] borate and a plasticizer 2-nitrophenyl octyl ether (NPOE) for the quantification of pharmaceutical bitterness maintains a stable response before and after accelerated deterioration, as well as high selectivity and sensitivity.
