Background: The nanocomposites are formed by introducing inorganic nano-clusters, fullerenes, clays, metals, oxides with numerous organic polymers. The assembly of these materials exhibits better properties such as catalytic, thermal stability and adsorption properties, than the individual materials.

Objective: The nanocomposite synthesized here by the sol-gel method was primarily evaluated for cation exchange properties viz, elution concentration, elution behavior, and the effect of temperature on ion-exchange capacity. The synthesized composite was used as an electroactive component for the fabrication of the Hg2+ ion-selective membrane electrode.

Methods: The sol-gel technique was used to synthesize multi-walled carbon nanotubes Zr(IV) phosphate composite cation exchanger. By the technique of solution casting, the material as an electroactive part was used for the fabrication of mercury ion-selective membrane electrode. The potential response of the electrode was also investigated as a function of membrane composition and plasticizer.

Results: The composite cation exchanger exhibited 1.8 meq g-1 ion-exchange capacity (IEC). It retained almost 65% of its initial IEC up to a temperature of 400°C. Distribution studies showed the selective nature of the composite for Hg(II) ions. The ion-selective membrane electrode exhibited a typical Nernstian response towards Hg2+ ions in the concentration range 1×10-1-1×10-7 M.

Conclusion: The results discussed reveal that the new cation composite exchanger-multi-walled carbon nanotubes Zr (IV) phosphate exhibited excellent cation exchange properties and was found to be preferentially selective towards the Hg2+ ions. It was also used as an indicator electrode in the titration of Hg2+ ions using ethylenediaminetetraacetic acid as a titrant.

Keywords: Cation exchanger, composite, Hg2+ ions, membrane electrode, multi-walled carbon nanotubes Zr (IV) phosphate, potentiometric determination.
