A stable, water-insoluable film was prepared by oxidative electropolymerization of pyrogallol in pH7.0 phosphate buffer solution, anti modified on a glassy carbon electrode surface by electrochemical method. The modified electrode was exploited for the selective preconcentration of Cu at a certain potential. The preconcentrated Cu was firstly reduced at a certain potential and then was determined by differential pulse stripping voltammetry.
