Abstract: Schiff base ligand (ST = N, N'-tetraethylenepentaminebis (salicylideimine)) was prepared by condensation reaction of salicylaldehyde (SA) and tetraethylenepentamine (TEPA), and further coordinated with iron (III) via coordination reaction to form a binuclear iron (III) complex, [Fe2(ST)(H2O)4]Cl4 (abbreviated as, Fe2(ST)). It was characterized by elemental analysis (EA), Fourier transform infrared spectrometer (FTIR), and ultraviolet-visible spectroscopy (UV-vis), etc. It was used as catalyst for the degradation of emerging contaminants, e. g., dibutyl phthalate (DBP) under visible light with hydrogen peroxide solution as oxidant. The results showed that at pH 3.5-8.0, with the initial concentration of Fe2(ST) complex larger than 5.50 mmol·L-1, and that of H2O2 larger than 8.16 mmol·L-1, the degradation of DBP at initial concentration less than 20.0 mg·L-1 can be reached to almost 100% within 10 min. The catalytic reaction system has been monitored by electronic spectrum before or af ter adding H2O2 at different time intervals. The result showed the catalytic activity site may be a m-N-bridged binuclear Fe(III) centre and a di-Fe(III)-H2O2 transition-state might be formed, which was favourable to the activation of the H2O2 under visible light. The Fe2(ST) is a potential effective and green catalyst for the degradation of DBP. (More)
