Magnetic vermiculite-modified (MV) by poly(trimesoyl chloride- melamine) (MP) was synthesized and used as a novel proficient adsorbent for the treatment of water/wastewater including bisphenol A (BPA) as a toxic pollutant. The MV-MP adsorbent was synthesized by loading of Fe2O3 nanoparticles and then modified with trimesoyl chloride and melamine by interfacial polymerization method. The developed adsorbent was analyzed morphologically and chemically by FTIR, SEM, as well as EDX techniques. The impacts of studied experimental parameters on the adsorption yield were examined by factorial design analysis. The isotherm model investigations showed that the Langmuir isotherms were the best fits for BPA compared to the Freundlich isotherm. The kinetic findings demonstrated that the pseudo-second-order (PSO) kinetic model showed a better correlation with the adsorptions of BPA than the pseudo-first-order (PFO) model. The thermodynamic results verified that the BPA adsorption on MV-MP was preceded via a spontaneous and exothermic process under the considered temperature conditions. The MV and MV-MP composites had excellent removal ability with a maximum adsorption capacity of 174.81 and 273.67 mg g(-1), respectively. The adsorbent had a considerable adsorption/desorption capacity after seven reuse cycles. By taking into account of all results, it can be concluded that the synthesized MV-MP composite is a promising adsorbent for the remediation of BPA from polluted water/wastewater.
