a Evolution of MO concentration in conditions of various radical scavengers. Ter-butanol, p-benzoquinone, AgNO3, and EDTA-2Na, are regarded as superoxide radical, hydroxide radical, electron, and proton scavengers, respectively. b Evaluation of the production of OH and O2 radicals and their reactivities by the fluorescence intensity of THA-OH and the absorbance of formazan dye, respectively. c Investigation of the influence of dissolved gas in solution on the degradation of MO. d Schematic of the effect of introducing ter-butanol on the production of DMPO adducts. e Measured EPR spectra under various conditions, and every peak is labeled by corresponding patterns. f Simulated EPR spectra under the same condition by EasySpin. Error bars represent standard deviation based on three replicate data.
