Study of Micellization of CTAB Using a Novel of Surfactant Membrane Ion Selective Electrode Based on Carbon Nano Tube

The use of the ion-selective electrode to study the equilibrium properties of aqueous surfactant solutions has received much attention in recent years [1-4]. Equipment costs are low and the construction materials generally available. The earlier electrodes were initially based around a poly (vinyl chloride) (PVC) membrane containing an active ionic species (ionophore) together with a suitable plasticizer. Charging of PVC is a difficult and harmful process. In this research we applied carbon nano tube (CNT) as ionophore. The proposed electrode was used successfully for direct determination of cationic surfactant in the water. Also stability of electrode is improved using our method.
