New Ion Selective Sensitive Electrode of Pd (II) as Multisensor Based onIRA-410 via Low Cost Oxidation Reduction Process

Abstract: A novel ion selective IRA-410 membrane disc sensor for Pd (II) ions has been prepared and studied. This electrode has a wide linear dynamic range from 10-1 to 2.5×10-6 mol-1 with a Nernstian slope of 16.5 ± 0.2 mV decade-1 and low detection limit of 1.6×10-6 mol l-1. It has a fast response time (<1 s) and good selectivity with respect to different metal ions. IRA-410 based electrode was suitable for aqueous solutions of pH range from (1.0- 9.0). It can be used for about 10 months with complex with Pd (II) was calculated by using segmented sandwich membrane method. The formation constant of ionophore of IRA-410 and its Pd (II)-Complex is examined using Fourier-transform infrared analysis and elemental analysis techniques. The proposed electrode has been used successfully as an indicator electrode in potentiometric determination in aqueous nitrate and /or chloride media.
