Abstract
The potentiometric response characteristics of cesium ion selective PVC membrane electrode employing calix[4]crown ether–ester as an ionophore were investigated. The electrode exhibit a good response for cesium ion over wide concentration range of 5.0×10−6–1.0×10−1 M with a Nernstian slope of 59 mV per decade. The detection limit of electrode is 5.0×10−6 M. The electrode was found to have selectivity for cesium ion over alkali, alkaline and transition metals. The response time of the electrode is less than 20 s and can be used for more than 4 months without observing any divergence in potentiometric response. The electrode response was stable over wide pH range.
