Figure 4.
(a) Effect of the pH on LS, as measured at 2 min after hydrogen peroxide addition. (0.3 μM FeMC6*a, 0.5 mM H2O2, 10 mM luminol, 100 mM Tris buffer). Dashed line corresponds to the best Gaussian fit of the experimental data. (b) Effect of luminol concentration on LS (0.3 μM FeMC6*a, 0.5 mM H2O2, 100 mM Tris buffer pH 8.5). Dashed line corresponds to the best biexponential fit of the experimental data.
