摘要：

Conditions were selected for the coulometric determination of copper(II) by titrating copper(II) 8-hydroxyquinolinate extracted to chloroform with electrochemically generated bromine. The procedure was tested on model solutions and samples of surface waters. The detection limit is 5 x 10-7 M at a generation current and time of 1 X 10-3 A and 10 s, respectively.
