Abstract:

A new Araldite matrix membrane electrode for Cu2+ and Ni2+ ion based on their Barium dichromate as membrane carrier as prepared. The Nernstian response for Cu2+ and Ni2+ ion over a wide concentration range of (1M-1x10-5M) with detection limits of the order of 10-5 M. The response time of the sensor is 40 seconds for Cu2+Ions and 52 seconds for Ni 2+ ions and membrane can be used for more than six month without observing any deviation. The proposed membrane sensor shows excellent discriminating ability towards Cu2+ and Ni2+ ions in comparison to several alkali, alkaline earth, transition and heavy metal ions. The effect of pH and effect of medium, selectivity co-efficient values have been found to give better responses.
