Abstrakt: The potential of the photocatalytic oxidation to selectively oxidise steroid estrogens, β-estradiol and 17α-ethynylestradiol, in the presence of saccharose and ethanol as co-pollutants was clearly demonstrated. The alkaline media conditions remained the most beneficial for the PCO regardless the presence of co-pollutants under consideration. Saccharose appeared to be the more powerful competitor than ethanol. The influence of the co-pollutants is explained by their competition for the adsorption sites and also scavenging of the OH-radicals. [ABSTRACT FROM AUTHOR]
