Abstract
A PVC-based membrane of dibenzodiazathia-18-crown-6-dione reveals a Nernstian potentiometric response for Hg2 over a wide concentration range (8.0610 ÿ6 to 1.0610 ÿ2 mol dm ÿ3). It has a response time of about 10 s and can be used for at least 3 months without any divergence. The proposed electrode revealed very good selectivities for Hg2 over a wide variety of alkali, alkaline earth, transition and heavy metal ions and could be used in a pH range of 0.5±2.5. It was successfully used as an indicator electrode in potentiometric titration of mercury ions.
