A new PVC mebrane electrode for iodide ions based on a recently synthesized salen-Mn9II) complex as membrane carrier was prepared. The electrode exhibits a Nernstian slope of 59.0=+0.4 mV per decade for 1- over a wide concentration range (1.0 x 10-1 --.4x 10-5M). It has a relatively fast response time of about 20 s and can be used for at least three months without any divergence in potential. The proposed sensor shows a fairly good discriminating ability towards 1- ion in comparison to other common anions. The electrode can be used in the pH range 3.5-8.5. It was used as an indicator electrode in potentiometric titration of iodide ion.
