Abstract

A new polyvinyl choloride (PVC) membrane sensor for cerium
(III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-
diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor
exhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with a
Nernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7
M. It has a fast response time (5 s) and can be used for two months
without any considerable divergence in its potential. The proposed
sensor revealed high selectivity toward Ce3+ ion with respect to some
alkali, alkaline earth and transition metal cations. It could be used in a
wide pH range of 2.0-11.0. The sensor was successfully used as an
indicator electrode in potentiometric titration of Ce3+ ion with
ethylenediaminetetraacetic acid (EDTA) and sodium iodide (NaI)
solutions, and in determination of Ce (III) concentration in real samples.
