  • The photochemical degradation of bisphenol-A(BPA) in aqueous solutions containing Fe(Ⅲ)-tartrate complex under the irradiation of a metal halide lamp was preliminarily investigated, and the effects of different factors such as light sources, the initial pH, the initial concentrations of Fe(Ⅲ), tartrate and BPA were discussed. The results indicated that BPA could be efficiently photooxidized by Fe(Ⅲ)-tartrate complex. The efficiency of BPA photooxidation could increase from 68.9% to 92.8% by increasing light intensity from 8.8×104 Lux to 1.2×105 Lux. BPA degradation efficiency and the concentration of ·OH generated from the process of Fe(Ⅲ)-tartrate complexes photolysis decreased with pH increase. pH value of the solution increased gradually in the process of BPA photooxidation. Excess tartrate was favour of the cycle of Fe(Ⅲ)/Fe(Ⅱ).
