Influence of pH and Concentration of Ionic Strength Adjuster (ISA) on the Performance of Nd(III) Ion Selective Electrodewith 4-Sebacoylbis(1-Phenyl-3-Methyl-5-Pyrazolone)(H₂SbBP) as Ionophores

Abstract:

4-Sebacoylbis (1-phenyl-3-methyl-5-pyrazolone) (H₂SbBP) ligand has been successfully synthesized, characterized and used as ionophores in Nd (III) selective electrode, using polytetrafluoroethylene (PTFE) membranous as a support. Prior to use the PTFE membrane soaked ionophores 1.5% w/v in chloroform for 24 hours. The performance of electrode studied by seeing the influence of pH and concentration of KNO₃ as a buffer solution ionic strength. Variations in pH of the solution was set at pH ranges between 1 to 10 using a solution of HCl and NaOH, while KNO₃ concentration varied between 10^-4 to 10^-1 M. Nd³⁺ concentration range is between 10^-6 up to 10^-2 M. The best electrode performance was obtained at pH 5 and 10^-2 M KNO₃ concentration with a sensitivity of (18.5 ± 0.2) mV/decade and its response time less than 25 seconds.
