Oxidative removal of sulfa antibiotics by introduction of activated carbon fiber to enhance the catalytic activity of iron phthalocyanine

As shown in figure, a possible pathway for the formation of active species was proposed in the ACF-FeTNPc/H2O2 system. In the ACFs-FeTNPc/H2O2 system, heterolysis of the O-O bond is dominant in the decomposition of H2O2, and produces active species of Fe(IV)] = O. A large number of free electrons exists in ACF and the electron transfer between ACF and FeTNPc is highly efficient, which indicates that FeTNPc exists with abundant electrons. This accelerates the homolysis of H2O2 and boosts the production of
- OH as accompanied by
- OOH. In the presence of H2O2, ACF-FeTNPc has a certain adsorption effect on SMX, while increasing the catalytic oxidation of SMX.202
