| Abstract: | Abstract— The quantum yield and the kinetics of O -induced luminol chemiluminescence was investigated in a broad pH interval at varying luminol and concentrations. It is suggested that the weak chemiluminescence observed is mediated via a luminol-superoxide-adduct proposed to be an a-hydroxyperoxyl radical. At pH 7 the maximum quantum yield of chemiluminescence per initial percent was determined to be 4 times 10-8. The degree of involvement in phagocytosis and related processes should be viewed against this maximum limit. |
