Abstract

An application of a sensitive apparatus with a photomultiplier (Iumino-photometer) for the measurement of chemical luminescence has been described. The reaction of luminol oxidation has been modified for the detection of trace amounts of H2O2, using haemin as catalyst; The stabilizing effect of the admixture of a complex salt of bivalent copper with tri ethanol amine on the haemin solution has been observed. The lower sensitivity limit has been found to be the concentration of 2 X 10-8 M H2O2 in the reacting medium. In conformity with previous studies the oxidation effects of the lowest concentrations of H2O2 cause a linear increase of the total intensity of the light emitted.
