Abstract

Some endocrine-disrupting compounds like 17β-estradiol, 17α-ethinylestradiol and 4-tert-octylphenol was removed from the surface waters using the N-BiOBr nanocomposite prepared under laboratory conditions. N doping on BiOBr improved the specific surface area and the photocatalytic activity of N-BiOBr. This phenomenon also decreased excessively the acute and chorinic toxicity originating from the 17β-estradiol, 17α-ethinylestradiol and 4-tert-octylphenol. The effects of N percentage removals of the removals of endocrine-disrupting compounds and activity on NBiOBr semiconductor was researched. The effects of N-BiOBr nanocomposite concentrations (0,5, 1, 1,5 and 2 mg/L), the effects of N percentages ( 2%,4%,6%,10%,15%) the effects of sun ligth power ( 1, 2, 4, 7 and 9 W/m2) and contacting times (10, 20, 30 and 40 min) on the of mineralization of endocrine-disruptings were studied. The toxicities performed by V. Fischeri and D. magna showed that the toxicities decreased from 98% to 8% at N-BiOBr nanocomposite concentration of 1,5 mg/l,at a N percentage of 10% after a sun ligth power of 4 W/m2 ana afte 30 retention time under sunligth. By doping BiOBr with N an effective photocatalytic removal process was tedected. Under optimized conditions; 17β-estradiol, 17α-ethinylestradiol and 4-tert-octylphenol were photocatalically removed with yield as high as 99%, 98% and 97%,respectively.
