Abstract
The development of a mercury-free electrochemical sensor for the detection of Cu(II) is described. In particular screen-printed carbon-based electrodes were modified with a membrane constituted by Nafion™ containing a macrocyclic polyamine derivative. The "medium exchange technique" was used to develop a procedure of accumulation of metal ions followed by square wave anodic stripping voltammetry (SWASV).
