Novel N,N’-bis(2,4-dimethoxybenzylidene)ethylenediamine PVC membrane electrode for the potentiometric iron selective sensor based on Schiff base ligand

Abstract

N,N’-bis(2,4-dimethoxybenzylidene)ethylenediamine was synthesized and used as a membrane carrier to create a novel poly(vinyl chloride) membrane potentiometric sensor that is selective especially for Fe3+ ions. The super-Nernstian slope of the projected sensor was 19.5 mV per decade over a concentration range of 7.3·10−8 –1·10−1 M having detection limit at 7.3·10−8 M. The sensor displayed a linear potential response for the detection of Fe3+ ions in about 30 seconds, and it had a lifespan of no less than 9 weeks without lacking any potential divergence. The selected sensor showed high selectivity in water solutions in relation to Fe3 + ions, even in the presence of other metal cations in the pH range of 3.6–10.
