(a) The time-dependent absorbance changes of ABTS·− corresponding to different concentrations of Initiator. (b) The calibration curve of the absorbance changes observed after a fixed time interval of 180 s vs varible concentrations of Initiator. Inset shows the linear relationship between the absorbance value of the oxygenation product ABTS·− (λmax = 420 nm) at the 180 seconds time point and the logarithm of Initiator concentrations. The error bars represent the standard deviation of the three measurements.
