Abstract
N
1, N
2-bis(salicylidine)butane-1,4-diamine (SAB ) based PVC membrane sensor was fabricated for Nd(III). The developed sensor showed nernstian response in the concentration range of 1.0×10
-6 to 1.0×10
-1 M. Nernstian slope of the proposed sensor was found to be 20.6±0.3 mV/decade in the pH range 3.0 to 7.5. The developed sensor displays a response time of <15 s. The proposed sensor can be used over a period of 7 weeks without any significant changes in its Nerstian behaviour. The sensor showed good selectivity for neodymium when compared with other metal ions such as Na
+, K
+, Mg
2+, Ca
2+, Pb
2+, Ag
+, Pr
3+, Sm
3+, La
3+, and Gd
3+. This electrode was used as an indicator electrode in the potentiometric titration of neodymium ions with EDTA and was also applied in the determination of neodymium in binary mixture.
