Electrochemiluminescent Detection of Hydrogen Peroxide via Some Luminol Imide Derivatives with Different Substituent Groups

Figure 4

Calibration curves for hydrogen peroxide detection. The measurements were performed in PBS buffer (pH 8.0) containing Lu-P-Ben at concentrations of 50 uM. The ECL reaction was initiated by sequential injections of hydrogen peroxide in the working medium at volumes of 10 uL (a), 20 uL (b), 30 uL (c), and 40 uL (d), respectively.
