Fig. 2: Identification of active oxidants and evolution of PCDD/Fs in the incidental Fenton-like catalytic system.

a EPR spectra of different oxidation systems. b Effect of different scavengers on the kinetics of TEQ reduction. c Change of the TEQ value of PCDD/Fs during oxidation. Default conditions: T = 293 ± 1.0 K; pH = 6.0 ± 0.3; [H2O2] = 50 mM; [fly ash] = 10 g L-1. For a: [DMPO] = 100 mM. The error bars represent the standard deviations from triplicate tests.
