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
to 1.0×10
M, with a Nernstian slope of 18.0±1.0 mV/decade,
and a detection limit of 9.7×10
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 Ce
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 Ce
ion with ethylenediaminetetraacetic acid
(EDTA) and sodium iodide (NaI) solutions, and in determination of Ce (III)
concentration in real samples.
