Abstract

A novel adsorbent successfully synthesized using recyclable silica, nano magnetite and N1-(3 trimethoxisilylpropyl) diethylenetriamine (TRIS) denoted as MNCMT. Three endocrine disrupting compounds (EDCs) such as bisphenol A (BPA), ibuprofen (IBP) and clorofibric acid (CFA) were selected as model drugs for this study. The sorption capacities of EDCs by MNCMT were found to be 182.6 mg g(-1) for BPA, followed by CFA at 101.8 mg g(-1) and 72.6 mg g(-1) for IBP. The removal process matched with Langmuir isotherm and pseudo second order kinetic models with determination coefficient (R-2) above 0.99. The adsorbent was regenerated, recovered and reused for multiple cycles of adsorption. The physical-chemical properties and experimental data revealed that the chemical sorption is more dominant than physical sorption. Hydrogen bonding, pi-pi and electrostatic attractions provide intrinsic information on the removal mechanism.
