“…Ion selective electrodes consist of a thin membrane across which only the intended ion can be transported. In the case of a potentiometric electrode, a potential develops in the presence of one ion but not in the presence of a similar concentration of other ions [32][33][34].…”

A desktop experiment has been done to show the nonlinearity in the I-V characteristics of an ion conducting electrochemical micro-system. Its chaotic dynamics is being reported for the first time which has been captured by an electronic circuit. Polyvinylidene fluoride-cohexafluoropropene (PVdF-HFP) gel electrolyte comprising of a combination of plasticizers (ethylene carbonate and propylene carbonate) and salts have been prepared to study the exchange of ions through porous poly ethylene terephthalate (PET) membranes. The nonlinearity of this system is due to the ion exchange of the polymer gel electrolytes (PGEs) through a porous membrane. The different regimes of spiking and non-spiking chaotic motions are being presented. The possible applications are highlighted.

“…It is well known that, not only the nature of ionophore, but also the membrane composition and the properties of the plasticizer and additive affect on the sensitivity and selectivity of ISE. [22][23][24][25] The performance characteristics of several membranes having ingredients of different proportions are listed in Table 1 ). Moreover, the amount of PQDBP was affecting the sensitivity of the membrane electrodes.…”

A PVC membrane electrode for lead ion based on 1-phenyl-2-(2-quinolyl)-1,2-dioxo-2-(4-bromo) phenylhydrazone (PQDBP) as ionophore was demonstrated. The optimum composition of the membrane was 30 wt% poly(vinyl chloride), 60 wt% dibutyl phthalate as a plasticizer, 4 wt% ionophore and 6 wt% sodium tetraphenylborate as additive. The electrode exhibits a Nernstian response (28.7 mV decade −1 ) for Pb 2+ over a wide concentration range (1.0 × 10 −1 to 1 × 10 −6 M) with a detection limit of 6.0 × 10 −7 M. This sensor has a short response time and can be used for at least 2 months without any divergence in potentials. The proposed electrode could be used in a pH range of 3.0-6.0 and revealed good selectivities for Pb 2+ over a wide variety of other metal ions. It was successfully applied as an indicator electrode for the potentiometric titration of lead ion with potassium chromate and for the direct determination of lead in mine.

“…Since the sensitivity and selectivity obtained for a given ionophore depend significantly on the membrane ingredients and the nature of solvent and additives used, [11][12][13][14][15] we investigated the influence of membrane composition on the potential response of the Ag + sensor. The effect of plasticizers (DBP, BA and NPOE), additives (NaTPB and KTK) and amount of ion-carrier on the performance of the membranes were studied and, the results are given in Table 1.…”

M. The sensor has a very fast response time (~5 s) in the concentration range of ≤ = 1.0 × 10 −3 M, and a useful working pH range of 4.0-9.5. The proposed sensor displays excellent discriminating ability toward Ag + ion with respect to common alkali, alkaline earth, transition and heavy metal ions. It was used as an indicator electrode in potentiometric titration of Ag + with EDTA and in direct determination of silver ion in wastewater of silver electroplating.
