(a) Schematic illustration of the mechanism of the influence after adding SCN-. Red ball: Fe, gray ball: C, blue ball: N, white ball: H, pink ball: O, yellow ball: S. (b) Absorption change of Fe-SASC/NW/TMB/H2O2 solution upon the addition of KSCN with various concentrations. (c) The percent inhibition and absorbance of Fe-SASC/NW/TMB/H2O2 solution after adding the ·OH/1O2 scavenger NaN3. (d) The absorbance of Fe-SASC/NW/TMB/H2O2 solution after adding isopropanol. (e) The formation of •OH using different concentrations of TA as a fluorescent probe.
