Abstract

 A NEW POLY (VINYL CHLORIDE) (PVC) MEMBRANE ELECTRODE BASED ON AN IONIC LIQUID, 1-HEXYL 3-METHYLIMIDAZOLIUM HEXAFLUOROPHOSPHATE, AND OLEIC ACID (OA) AS A GOOD LIPOPHILIC ADDITIVE FOR HIGHLY SELECTIVE DETERMINATION OF PB2+ ION HAS BEEN DEVELOPED. THE ELECTRODE EXHIBITS A NERNSTIAN SLOPE OF 30.9 MV DECADE-1 OVER WIDE PB2+ CONCENTRATION RANGE FROM 1×10-6 TO 1×10-2 M AND LOW DETECTION LIMIT 1.58×10-7 M. THE ELECTRODE POSSESSES A FAST RESPONSE TIME OF ~20 S, RELATIVELY LONG LIFETIME (AT LEAST 3 MONTHS). THE PROPOSED ELECTRODE REVEALED EXCELLENT SELECTIVITY FOR PB2+ OVER A WIDE VARIETY OF ALKALI, ALKALINE EARTH, SOME TRANSITIONS AND HEAVY METAL IONS. THE ELECTRODE COULD BE USED IN A PH RANGE OF 4.0 TO 10.
