A POLY (VINYL CHLORIDE) BASED MEMBRANE ELECTRODE FOR THE SELECTIVE DETERMINATION OF Zr(IV)
Aishwarya Singh & D.S.Tyagi
 
ABSTRACT
A new Schiff base chelating ligand 1-(1H-indol-1-yl)-N-(thiophen-2-ylmethyl) ethanimine have been synthesized and used as electroactive material for the selective determination of Zr(IV). The membrane electrode has a wide linear concentration range of 2.0 x 10-8 M to 1.0 x 10-1M with a fast response time of about 5s and cloud be used in a pH range of 3.5 -7.6 without divergence in response characters. The membrane electrode was used for the determination of Zr(IV) in various samples and the values were also compared with those obtained by AAS and ICP-MS.
