of luminol and O2
radicals (4) further reaction of the luminol and
O2
radicals generates the excited state 3-aminophthalate (3-
AMP*
) which is the luminophor and could enhance CL of the system
[39,41].
In the present work, in order to study the possible CL mechanism
and the role of CuO nanosheets, UV–Vis absorption (Fig. 5)
and CL spectra (Fig. 6), in addition to CL intensity-time curve
(Fig. 3), were recorded for the luminol–H2O2 CL system in the presence
and absence of CuO nanosheets and cloxacillin sodium. Fig. 5
