The Cu 2+ ‐imprinted cross‐linked chitosan resin was synthesized and the binding characteristic of the resin to Cu 2+ was evaluated. The prepared resin was packed into a micro‐glass column and used as micro‐separating column. The micro‐separating column was connected into the chemiluminescence flow system and placed in front of the window of the photomultiplier tube. Based on the luminol–hydrogen peroxide chemiluminescence system, a flow injection online chemiluminescence method for determination of trace copper was developed and trace Cu 2+ in complex samples was successfully determined. The proposed method improved the shortcomings of chemiluminescence method's poor selectivity. Copyright © 2010 John Wiley & Sons, Ltd.
