dc.description.abstractPoly(vinyl chloride) supported tetracycline sorbed zirconium(IV) selenomolybdate chelating inorganic exchange membrane has been employed for the determination of dysprosium(III) ion. The membrane electrode shows a Nernstain response for Dy(III) over a wide concentration range (l.0×10-1 M - 5×10-5 M) with a slope of 18.3 mV per decade of concentration. The detection limit is 3.8×10-5 M. The electrode is found to possess adequate stability and specific selectivity for Dy(III) over the other closely trivalent lanthanide metal ions with a response time of ~15 s. The sensor can also be used in partially non-aqueous medium, e.g., acetone/alcohol having 5- 10% (v/v) contents. Its working pH range is 2-9. It is successfully applied for the direct determination of Dy3+ in meta borate rock and as an indicator electrode in potentiometric titrations of dysprosium ion with 2-4 % experimental error.en_US
