This work investigates the use of electronic tongues for environmental monitoring. Electronic tongue was based on arrays of potentiometric sensors plus a complex data processing by artificial neural networks. Special attention was paid in compensating temperature effects and possible drifts in the sensors response. In addition, and to demonstrate viability of the proposed systems for automated ...

A cationic surfactant-selective electrode for sensitive analysis of cationic surfactant has been developed by using a plasticized poly (vinyl chloride) membrane based on nanocomposite cation exchanger polypyrrole zirconium titanium phosphate. The electrode is excellently selective for the cetyl trimethyl ammonium bromide (CTAB) ion over inorganic ions and other cationic surfactants. The membran...

a new cesium ion selective pvc membrane based on parent calix [4] arene was developed for potentiometric determination of cesium in environmental samples. the electrode based on p-5,11,17,23tetra(tertbutyl) 25,26,27,28-tetrahydroxy calix[4]arene(thc) as ionophor ,dibutyl phthalate (dbp)as plasticizer ,sodium tetra phenyl borate(natpb)and oleic acid as lipophilic salt and additive showed the bes...
