Estimation of heavy metals in water has been paid significant attention because of the toxicity of such metals on the whole ecological system. A microelectrode array (MEA) of individually addressable microelectrodes was fabricated for cadmium, lead and copper analysis in water pollution. The ratio of interelectrode distance to the electrode diameter of the MEA was sufficient enough to get a collective current response while maintaining the excellent features of single microelectrodes. Cyclic voltammograms made in...
