The authors present a detailed study of the chemiluminescence of ruthenium tris-2,2'-dipyridy1 complex Ru(bipy)/sub 3//sup 2/ in the system potassium bromate-malonic acid-cerium (III, IV) sulfate. It is found that chemiluminescence of dipyridy1 ruthenium compounds in the BrO/sub 3/-reverse arrow CH/sub 2/(COOH)/sub 2/-Ce (III) system enables the detection of the element at very low concentrations (down to about 2.10/sup -10/ M). The dependence of the maximum intensity on ruthenium concentration is linear over a wide range (2.10/sup -10/-10/sup -4/ M). The high intensity in this system is due to the repeated chemical excitation of the ruthenium ion during a single oscillation period.
