Abstract

Endocrine disrupting compounds (EDCs) present serious environmental problems due to their negative impacts on lifeforms. To solve these issues, a metal–organic frameworks (MOF) was used as an efficient adsorbent for the removal of EDCs. This work was mainly conducted to (i) characterize the adsorbent, (ii) establish the feasibility of MOF for removal of the selected EDCs (bisphenol A (BPA), 17α-ethynylestradiol (EE2), and perfluorooctanoic acid (PFOA)), and (iii) study the competitive adsorption mechanism. Physicochemical properties of MOF were characterized by microscopy, porosimetry, and zeta potential analyses. Feasibility testing of MOF was conducted under various solution conditions to determine the effect of solution temperature, pH, background ions, and humic acid on the adsorption capacity. The adsorption process in this study was spontaneous reaction, considering the negative value of ΔG⁰ derived from experiments of solution temperature. According to experimental results related to the adsorbent dose, the maximum equilibrium adsorption capacity (q_e) for BPA, EE2, and PFOA by MOF was 138.4, 200.4, and 169.2 mg g⁻¹, respectively. The adsorption mechanism of the EDCs was clearly explained by numerous solution factors (i.e., pH, background ions, and the existence of humic acid), and synergetic effects of hydrophobic and electrostatic interactions were important to explain the adsorption mechanism.
