Sorption of bisphenol A, 17α-ethynylestradiol and estrone to mineral surfaces Academic Article uri icon

abstract

  • Sorption of the endocrine disrupting chemicals (EDCs) bisphenol A (BPA), 17alpha-ethynylestradiol (EE2) and estrone (E1) from 3 microM aqueous solutions in 10 mM KNO3 to goethite, kaolinite and montmorillonite was investigated at 25 degrees C. Uptake of the EDCs by goethite and kaolinite suspensions was <20%, and little affected by pH. Sorption by montmorillonite was greater, ranging from 20 to 60%, and steadily increased from about pH 7. The amount of EDC sorbed to the mineral phases generally increased in the order of decreasing solubility (BPA
