The fluorimetric determination of hydrogen peroxide by using the fluorescence reaction between N-(4'-hydroxyphenyl)-N-(4-methylquinolinyl)amine (HPMQ), cobalt(II) and hydrogen peroxide in the presence of trimethylstearylammonium chloride (STAC) as a cationic surfactant was proposed. The calibration graph was linear in the range 0-2500 ng of hydrogen peroxide per 10 ml of solution at an emission wavelength of 522 nm with excitation at 410 nm. The recovery tests in foods were good.
