N,N'-bis(2,4-dimethoxybenzylidene)ethylenediamine was synthesized and used as a membrane carrier to create a novel polyvinyl chloride) membrane potentiometric sensor that is selective especially for Fe~(3+) 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 Fe~(3+) 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 Fe~(3+) ions, even in the presence of other metal cations in the pH range of 3.6-10.
