Abstract

A polyvinyl chloride (PVC) based membrane sensor for terbium ions was prepared by employing Hematoporphyrin (HP) as an ionophore. The sensor revealed a very good selectivity (expect for the Fe3+ion) with respect to common alkali, alkaline earth and heavy metal ions. The plasticized membrane electrode exhibits a Nernstian response for Tb3+ ions over a wide concentration range (1.0 × 10−6 − 1.0 × 10−2 M) with a slope of 19.8±0.3 mV per decade and low detection limit of 7.4 × 10−7 M. The developed sensor was used in determination of F in mouth wash preparation sample.

The authors gratefully acknowledge the financial support of this research proposal, provided by the Research Council of the Quchan Islamic Azad University.
