Removal of 17β-oestradiol and 17α-ethinyl oestradiol from water by activated carbons and hypercrosslinked polymeric phases

摘要: Abstract There has been growing concern about man-made and naturally occurring chemicals in the environment recent years. These interfere with hormone (or endocrine) system, suggesting far-reaching effects on reproduction development current future man wildlife generations. Recent research highlighted existence of these substances sewage industrial effluents their potential for recycling back into environment, including drinking water, through point non-point sources. 17β-Oestradiol (E2) 17α-ethinyl oestradiol (EE2) are amongst compounds since they were found to cause adverse fish even at low concentration levels. In this work, adsorption E2 EE2 onto several granular activated carbons Macronet polymers was investigated by batch experiments after a level detection system developed using Gas Chromatography Mass Spectrometry (GC/MS). Equilibrium carried out all adsorbents quantify sorption capacity data correlated conventional theoretical treatments. For better assessment sorbents, physical properties surface area, average pore diameter micropore volume chemical structure characterised N 2 experiments. Further characterisation performed scanning electron microscopy (SEM), FTIR spectroscopy, sodium determination, pH titration, proton-binding curves zeta measurements. Kinetic different size ranges results analysed applying particle diffusion model. This study demonstrates removal endocrine-disrupting from aqueous solution.
