“…The electrode was characterized on the basis of different parameters like response time, measuring range and slope of calibration curve. The effect of According to IUPAC recommendations, the detection limit is defined by the cross section of two extrapolated linear calibration curves [27,28] and was found to be 1.0 × 10 -6.5 M. The potential response of the sensing behaviour of the electrode remained same whether the EMF was measured from higher to lower or lower to higher concentration [29]. Potential response of the sensor was tested for other cations like Pb(II), La(III), Cd(II), Co(II), Hg(II), As(III), Cu(II), Ni(II), Mn(II), Sm(III) etc.…”

Ion selective electrode based on chromium(III) boratotungstophosphate was successfully fabricated for the detection of Hg(II) ions. The characterization of electroactive material has been done with FTIR, SEM, EDS and X-Ray diffraction studies. Polymeric membranes containing different composition of electroactive material and epoxy resin as binder were prepared. The best performance was shown by the electrode with composition having 40 % electroactive material and 60 % epoxy resin. A reasonably short response time of 6 s was shown together with a life of six months without any divergence in potential. The sensor possessed a near Nernstian slope of 25 ± 0.8 mV decade-1 over a wide linear range of 1.0 × 10-1 M − 1.0 × 10-6 M Hg(II) ions. The electrode worked satisfactorily in the partially nonaqueous medium also. The working pH range of the sensor was found to be 2.43-8.0. Analytical applicability of membrane sensor was evaluated by using it as an indicator electrode for analysis of Hg(II) ions in different water samples procured from sea and canal waters. The proposed electrode displayed good selectivity for Hg(II) in the presence of some transition metal(II) ions and lanthanide(III) ions.

The novel exchanger titanium(IV) tungstovanadate has been prepared by sol-gel method. The characterization of sensor has been done with FTIR, SEM, EDS and X-ray diffraction studies. Membranes containing different composition of electroactive material and epoxy resin as binder were prepared. The membrane with 60 % electroactive material and 40 % epoxy binder gives the best response. Potentiometric result shows that the sensor can be used in the concentration range of 10-7 to 10-1 M Cd(II) ions with a near Nernstian slope of 21 mV/ decade. The electrode shows a fast response time of < 10 sec. The working pH range of the electrode is 2.62 to 8.66 and it behaves well in the partially non aqueous medium upto 30 % concentration of ethanol, methanol and acetone. Fixed interference method was used for determining the selectivity coefficient with respect to different metal ions like Pb 2+ , Cr 3+ , La 2+ , Co 2+ , Hg 2+ , As 3+ , Cu 2+ , Ni 2+ , Mn 2+ , Sm 3+ etc. and effect of internal solution was also studied. The developed sensor can be used as an indicator electrode in the potentiometric titration of Cd(II) against EDTA and oxalic acid.
