The effect of the Fenton reagent on CYN degradation by Fenton process at H2O2/Fe(II) molar ratio of 0.4. (a) relative residual concentration (C/C0) of CYN, H2O2, and Fe(II) and (b) pH-time profile. (Initial CYN concentration ≈ 0.05 μM. The values are averages of three replicates, and error bars indicate the standard deviation).
