A PVC membrane electrode based on copper(Ⅱ) bis(N-2-bromophenylsalicyldenaminato) as ionophor was prepared.The ion selective electrode was tested by inorganic anions and showed a good selectivity for iodide ion.This sensor exhibited Nernstian behavior with a slope of—57.8 mV per decade at 25℃.The proposed electrode showed a linear range from 1.0×10~5 to 1.0×10~(-1) mol/L with a detection limit of 5.0×10~(-6) mol/L.The electrode response was independent of pH in the range of 3.0- 10.0.The proposed sensor was applied to determine the iodide in water and antiseptic samples.
