This paper is devoted to investigate the suitability of cellulose for estrogens micropollutants removal from water effluent. For this purpose, the sorption of eight estrogens including Estradiol, Estrone, Testosterone, Progesterone, Estriol, Mestranol, Ethinylestradiol and Diethylstilbestrol were investigated. The charge density profiles and sorption curves were obtained and discussed using quantum chemical calculations where the Accelrys Materials Studio software and COSMO-SAC model were employed. The geometry optimization of compound molecule and energy minimizations was performed using the Dmol3 Module and density functional theory of generalized gradient approximate and Volsko-WilkNusair functional. We found that cellulose cannot be a reliable choice of sorbent for removal of Estrone and Estradiol, but it is a poor choice of sorbent for removal of Estriol, Ethinylestradiol. Cellulose can be used for Diethylstilbestrol, Mestranol, Testosterone and Progesterone removal from estrogens containing effluents. (C) 2017 Elsevier Ltd. All rights reserved.
