摘要：

A new Cu2+ carbon paste electrode (CPE) using 2,2'-(1E,1'E)-1,1'-(2,2'-azanediylbis (ethane-2,1-diyl) bis(azan-1-yl-1-ylidene))bis(ethan-1-yl-1-ylidene)diphenol (ADEZEDP) has been prepared. The influence of variables including sodium tetraphenylborate (NaTPB). ionophore, and amount of multiwalled carbon nanotubes (MWCNT). CdO nanowires, CdS nanoparticles and palladium nanoparticles loaded on ADEZEDP and Nujol on the electrodes response were studied and optimized. At optimum values of all variables, for each nanomaterial the electrode response was linear in concentration range of 1.0x10(-8) to 1.0x10(-1) mol L-1 for ADEZEDP with Nernstian slope. The good performance of electrode viz. Wide applicable pH range (2.0-5.0), fast response time (approximate to 6 s). and adequate life time (3 months) indicate the utility of the proposed electrodes for evaluation of Cu2+ ion content in various situations. Finally, these electrodes have been successfully applied for the determination of Cu2+ ions content in various real samples. The selectivity of proposed electrode was evaluated by separation solution method and fixed interference method. (C) 2012 Elsevier B.V. All rights reserved.
