Influence of different plasticizers on the response
1.. IntroductionPlasticizers play an important role in the behavior of polymeric liquid membrane ion-selective electrodes (ISEs). For a plasticizer to be adequate for its use in a polymeric liquid membrane ion-selective electrode, it should gather certain properties and characteristics such as having high lipophilicity, high molecular weight, low tendency for exudation from the polymeric
Plasticizers for liquid polymeric membranes of ion-selective
Plasticizers for liquid polymeric membranes of ion-selective chemical sensors. A variety of 55 different plasticizers based on various structural elements were investigated in respect to their applicability in liquid polymeric membranes of chemical sensors. The plasticizers and the overall performance of the membrane were judged in respect to
Polymeric plasticizer extends the lifetime of PVC-membrane
The nature of the plasticizer plays a pivotal role in the analytical performance of polymer membrane ion sensors. Conventional plasticizers suffer leaching or migration from the membrane and exudation, both of which could limit the lifetime of sensors based on plasticized membranes. Herein, we describe the u

- How important are plasticizers in the preparation of membranes for ion-selective electrodes?
- We presented here the importance and proper use of plasticizers in the preparation of membranes for ion-selective electrodes. The nature of the plasticizer influences key performance indicators of the ion-selective membrane electrodes such as slope, the domain of linear response and the selectivity.
- Which plasticizers should be used in ion-selective electrode preparation?
- The plasticizers used in the preparation of the polymeric membrane of ion –selective electrodes must be compatible with the polymer and electrodic component and also must be solved in tetrahydrofuran or cyclohexanone, the solvent used in the membrane preparation. The plasticizers with high lipophilicity are preferred.
- How to choose the best plasticizer for a polymeric membrane?
- The selection of the best plasticizer for the development of a polymeric membrane specific to a certain ion usually involves experimental tests in order to find the plasticizer and the ionophore with which the best response characteristics of the ion -selective electrodes are obtained.
- What are the properties of a plasticizer used in membrane preparation?
- The desirable properties of a plasticizer used in the membrane preparation of the ion- selective electrodes are: compatibility with the polymer, low volatility and low solubility in aqueous solution, low viscosity, low cost and low toxicity (O’Rourke et al., 2011).
- Do plasticizers affect the performance of polymer membrane ion sensors?
- The nature of the plasticizer plays a pivotal role in the analytical performance of polymer membrane ion sensors. Conventional plasticizers suffer leaching or migration from the membrane and exudation, both of which could limit the lifetime of sensors based on plasticized membranes.
- Are plasticizers used in organic solvent membranes a good choice?
- It was concluded that plasticizers used in organic solvent membranes have to fulfill many criteria, e.g. high lipophilicity, solubility in the polymeric membrane (no precipitations) as well as no exudation (one phase system) and a good selectivity of the resulting membrane.
