Abstract
A study was conducted for the adsorption of Bisphenol A (BPA) from aqueous solution using solvent impregnated resin (Amberlite XAD-7 was impregnated with trioctylphosphine oxide). FTIR, FE-SEM and EDX analysis characterized this prepared resin. Various parameters like contact time, the mass of adsorbent, BPA initial concentration, and the temperature was studied. For impregnated resin percentage removal was obtained 88.09% within 120 min. For BPA adsorption, optimum adsorbent dosage was found to be 8 g·L -1 . Adsorption of BPA decreased with increase in temperature. Different models like Langmuir, Freundlich and Temkin models were used to predict the equilibrium points. Kinetics of BPA adsorption was predicted using pseudo-first order, pseudo-second order, and intraparticle diffusion models.
