Abstract

Tri butyl phosphate (TBP) is a plasticizer composed of organic substances that can be added to poly vinyl chloride (PVC) in order to improve its elasticity. When designing a selective polymeric membrane for potentiometric electrochemical sensors, plasticizers play a crucial role. Plasticizers increase the device's selectivity by modifying the membrane's dielectric constant. Potentiometric analysis and other analytical applications, including environmental and pharmaceutical analysis, employ instruments called ion-selective electrodes. Rapid response, elongated lifetime, sensibility, and selectivity for ion-selective electrode depend on the plasticizer type, electrode type, and the additive used in the construction of an ion-selective electrode. Numerous parameters, including the area of linear response, slope, and selectivity, are impacted by the plasticizer. The ionosphere and polymer must be compatible with the plasticizer in the membrane. One appropriate plasticizer for the creation of ion-responsive, selective electrodes is tri-butyl phosphate (TBP).
