Abstract :
A PVC membrane Fe(III) ion selective electrode has been constructed using a new macrocyclic as
membrane carrier.The electrode exhibits a good potentiometric response for Fe(III) over a wide
concentration range 1.0×10-4 to 1.0×10-1M with a slope 19.4±0.5 mV/decade a and a working pH
range of 6.5-9.0. It has a fast response time ≤30s.The best performance was observed with the
membrance having the 30.5% PVC,3.0% ligand, 61.0% acetophenone and 5.5% oleic acid
composition.
