A new plasticized PVC uranyl-selective electrode based on a bis(2-hydroxyacetophenone)ethylene-diimine (BHAED) carrier by the direct coating of the membrane ingredients on the surface of a graphite disk electrode is reported. The electrode displayed high selectivity for uranyl ion toward a number of inor-ganic ions. The influence of the membrane compositions and pH, the effect of lipophilic cationic and an-ionic additives and plasticizer on the response properties of the electrode were investigated. The electrode exhibited a Nernstian slope of +29.3 ± 1.2 for the uranyl ion concentration in the range of 5. 10 -6 -0.05 M with detection limits of approx. 2.0 mM. The potentiometric responses of the electrode are independent of pH over the range of 3.0-4.5 with satisfactory reproducibility. The sensor has response times of <5 s and can be used for at least 2 months without considerable divergence in potential. electrode bis(2-hydroxyacetophenone)ethylenediimine (BHAED); Poly vinyl chloride (PVC).
