| Abstract: | A Mg(II) ion sensor selective araldite zirconium(IV) selenomolybdate membrane sensor is prepared. It exhibits slope 23 mV/decade, which is a sub-Nernstain slope. The sensor shows working concentration range as 1.0 × 10-5 M to 1.0 × 10-1 M and working pH range as 2.5 to 6.0. The selectivity coefficients for 17 metal ions are studied. It can be used in the presence of some solvents up to 10 per cent v/v concentration as well as in the presence of 10-4 to 10-6 M Na-lauryl sulphate surfactant. The membrane electrode is put in the determination of Mg(II) ion content in synthetic samples as well as in hard water samples. The error is found to be within 2 to 6 per cent. |
