摘要：

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 x 10(-6)-1.0 X 10(-1) M With a Nernstian slope of 59 mV per decade. The detection limit of electrode is 5.0 x 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. (C) 2002 Elsevier Science B.V. All rights reserved.
