“…13 Though the CL have many advantages, normally the amount of energy released during a chemical reaction dissipates as heat, therefore the chemiluminescence reagents having been investigated was limited. At present, the chemiluminescence reagents named luminol, [14][15][16] lucigen, 17,18 peroxidate, 19 tris(2,2 , -bipyridyl)ruthenium(II) 20,21 and potassium permanganate [22][23][24][25] have been widely used in analytical chemistry. Up until now, only one article had been published for the determination of cinnamic acid by CL method, and it was based on Ru(bipy) 3 2+ -KMnO 4 System.…”

Recebido em 21/2/11; aceito em 11/4/11; publicado na web em 10/6/11It was found that cinnamic acid can react with potassium permanganate in the acidic medium and produce chemiluminescence, which was greatly enhanced by glyoxal. Under the optimum conditions, the linear range for the determination of cinnamic acid was 1.0×10 -8 to 1.0×10-4 mol L -1 with a detection limit of 8.0×10 -9 mol L -1, the relative standard deviation was 1.7% for 2.0×10 -6 mol L -1 cinnamic acid solution in nine repeated measurements. This method was found to be novel、simple、fast and sensitive, it was successfully applied to the determination of cinnamic acid in human urine. Furthermore, the possible reaction mechanism was also discussed.
