The kinetic method is based on the catalytic effect of copper(II) on the atmospheric oxidation of 1,3-cyclopentanedione bis(4-methylthiosemicarbazone) monohydrochloride. The reaction is followed spectrophotometrically at 390 nm. The kinetic parameters of the reaction are reported and a rate equation is suggested. The calibration graphs are linear in the range 0.05–0.5 μg Cu ml−1. Interference by other ions is studied.
