As the chelating resin in the electrode can exerts a concerted effect of ion exchange and coordination with copper, this method produces a high sensitivity and selectivity.
The conversion of cyano group was measured indirectly by the adsorption capacity for copperof the chelating resin.

Pyridine amino resinof high selective absorption for copper ion was synthesized by the suspension method, and its absorption properties were evaluated by absorption experiment of copper ion.
