“…their ability to withstand ionizing radiations and high temperature, without undergoing degradation and their remarkably high selectivity [8]. In contrast to such operational problems, we hereby present a heterogeneous solid membrane electrode based on low solubility inorganic ion exchanger [9]. In ion exchange membranes, the charged groups attached to the polymer backbone are freely permeable to oppositely charged ions under influence of electric field [10][11][12][13].…”

Zirconium phosphoborate based heterogeneous membrane electrode has been used as a sensor for yttrium ions in aqueous medium. The electrode shows reproducible and Nernstian behavior for yttrium ions in the oncentration range 10-4M to 10-1M with an RSD of 2%. The electrode does not show any change in response within a pH range of 5-9. The effect of internal solution concentration on the calibration curve was also studied. The electrode performance was also studied in partially non-aqueous medium (5% - 20%) of acetone and ethanol. The system was used successfully as an indicator electrode in potentiometric titration of yttrium ions with EDTA.

A samarium(III) selective potentiometric sensor has been prepared on the basis of polyvinyl chloride (PVC) membranes containing an ion exchanger (zirconium boratophosphate) as an electro-active material. The best performance was exhibited by a membrane having the following composition: zirconium boratophosphate (10%) and poly vinylchloride (90%). This membrane works well over a wide concentration range (from 1 × 10 -5 to 1 × 10 -1 M) of Sm(III) ions with a Nernstian slope of 20.2 mV/decade. The response time of the sensor is 15 s, and the membrane can be used for more than six months with good reproducibility. Selectivity coefficients determined by the fixed interference method for a number of mono-, di-, and trivalent cations are reported. The sensor has also been used as an indicator electrode in the potentiometric titrations of samarium (III) ions with EDTA solution.
