Abstract

A deep eutectic solvent molecularly imprinted polymer (DES-MIP) was synthesized via bulk polymerization using bisphenol A (BPA) as the template, DES as the monomer, ethylene glycol dimethyl acrylate (EGDMA) as the cross-linker, and benzoyl peroxide (BPO) as the initiator. A hybridized deep eutectic solvent molecular-imprinted polymer membrane (HDES-MIP) was produced by hybridizing cellulose acetate (CA) with a previously prepared DES-MIP. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to analyze the fundamental functional groups and morphology of the synthesized membrane. Kinetic and isotherm analyses of the HDES-MIP membrane revealed that the data corresponded well with pseudo-second-order kinetic (R2 = 0.9986) and Langmuir isotherm models (R2 = 0.9983). The maximum adsorption capacity was observed at pH 8. A thermodynamic study of the HDES-MIP membrane showed that the adsorption of BPA was exothermic and spontaneous. The development of a hybridized deep eutectic solvent molecular-imprinted polymer membrane (HDES-MIP) offers significant potential for the effective and environment-friendly removal of bisphenol A (BPA), emphasizing the importance of this research in addressing pollution concerns and advancing sustainable materials.
