✦ Synopsis

Hydrogen peroxide amplifies the chemiluminescence in the odixation of luminol by sodium hypochlorite. A linear relationship between concentration of hydrogen peroxide and light intensity was found in the concentration range 5 x 10-*-7.5 x mol/l. At 7.5 x l o -' mol/l H,Oz the chemiluminescence is amplified 550-fold. The chemiluminescence spectra of these reactions have a wavelength maximum a t 431 nm independent of the concentration of hydrogen peroxide. The results indicate that hydrogen peroxide is a necessary component in the chemiluminescent oxidation of the luminol by sodium hypochlorite.
