A sensitive differential pulse polarographic method is described for the determination of some chalcones. The analysis was performed in Britton-Robinson buffer at pH 2.0. The reaction mechanism is based on the reduction of carboxyl group present on the chalcones. The detection limit found was 1.0x10(-8) M, and the response was found to be linear up to 2.9 x 10(-5)M with the relative standard deviation (of the 2.0x10(-5)M level) 2.66%.
