摘要：
A new modified carbon paste electrode based on cyclam as a modifier was prepared for the determination of Co(I) ions. The proposed electrode shows a Nernstian slope 28.4 mV per decade over a wide concentration range 5.0 X 10(-6) - 1.0 X 10(-1) mol/L of Co2+ ions with detection limit 2.5 X 10(-6) mol/L. The sensor exhibits good selectivities for Co2+ over a wide variety of other cations. It can be used as an indicator electrode in potentiometric titration of cobalt(I) ions as well as in direct determination of cobalt(I) ions in wastewater of acidic cobalt electroplating bath. The electrode shows Nernestian behavior in a solution of 25% ethanol.
