Bis-picolylamine, iminodiacetate functionalized resins are efficient sorbents for Cu^2 + ions removal.

Rapid sorption properties of Cu^2 + ions by chelating resins

The resins are useful for the separation and preconcentration of copper ions.

All resins used are reusable and their capacity reductions are small.

The resin has high absorption capacity for Cu^2 + ions for a short resin contact times.
