Abstract
The intensity of 4‐I‐phenol‐enhanced chemiluminescence from the luminol‐H2O2‐horseradish peroxidase system is markedly attenuated in the presence of low concentrations of non‐enhancer phenols. Under the conditions studied, the effect is not associated with competition between 4‐I‐phenol and non‐enhancer phenol for the enzyme intermediates, Compounds I and II, but involves a competition between non‐enhancer phenol and luminol most probably for the 4‐I‐phenoxy radical.Keywords
