Selective Photocatalytic Oxidation of Steroid Estrogens in the Presence of Copollutants inthe Sanitary Fraction of Domestic Sewage

[摘要] The photocatalytic oxidation (PCO) of the steroid estrogens (SEs),β-estradiol, and 17α-ethynylestradiol, competitive with some constituent compounds of the sanitary fraction of domestic sewage, was studied. The copollutants, urea, and saccharose, present in concentrations exceeding those of the SEs by a factor of a hundred to thousands, appeared to exert a weaker influence to the photocatalytic degradation of the SEs than was expected. The removal of the SEs from diluted urine proceeded, selectively, demonstrating the potential of PCO in the treatment of the separate sanitary fraction of domestic sewage.
