A new activated carbon (AC) material was prepared by pyrolysis of a mixture of coffee grounds, eucalyptus sawdust, calcium hydroxide and soybean oil at 800 degrees C. This material was used as adsorbent for the removal of the endocrine disruptor compounds 17 beta-estradiol (E2) and 17 alpha-ethinylestradiol (EE2) from aqueous solutions. The carbon material was characterized by scanning electron microscopy (SEM), infrared spectroscopy (FTIR), N-2 adsorption/desorption curves and point of zero charge (pHpzc). Variables including the initial pH of the adsorbate solutions, adsorbent masses and contact time were optimized. The optimum range of initial pH for removal of endocrine disruptor compounds (EDC) was 2.0-11.0. The kinetics of adsorption were investigated using general order, pseudo first-order and pseudo-second order kinetic models. The Sips isotherm model gave the best fits of the equilibrium data (2981K). The maximum amounts of E2 and EE2 removed at 298 K were 7.584 (E2) and 7.883 mg g(-1) (EE2) using the AC as adsorbent. The carbon adsorbent was employed in SPE (solid phase extraction) of E2 and EE2 from aqueous solutions. (C) 2014 Elsevier B.V. All rights reserved.
