Modeling of methylene blue adsorption using functionalized Buckypaper/Polyvinyl alcohol membrane via ant colony optimization. Environ Pollut. 2020 Jan 08;259:113940 Authors: Jua LY, Karri RR, Mubarak NM, Yon LS, Bing CH, Khalid M, Jagadish P, Abdullah EC Abstract Jicama peroxidase (JP) was covalently immobilized onto functionalized multi-walled carbon nanotube (MWCNT) Buckypaper/Polyvinyl alcohol (BP/PVA) membrane and employed for degradation of methylene blue dye. The parameters of the isotherm and kinetic models are estimating using ant colony optimization (ACO), which do not meddle the non-linearity form of the respective models. The proposed inverse modeling through ACO optimization was implemented, and the parameters were evaluated to minimize the non-linear error functions. The adsorption equilibrium was best described by the Freundlich isotherm model, whereas, the Lagergren pseudo 1st order kinetic model described the adsorption process with good fitting. Besides, the thermodynamic studies indicated that the adsorption was favourable, spontaneous, and exothermic in nature. The comprehensive structural analyses using several characterization studies were performed, including fluorescence microscopy, Fourier transform infrared spectroscopy (FTIR), and Field emission scanning electron microscopy (FESEM). These analyses have confirmed the successful binding of peroxidase onto BP/PVA membrane, as well as the effective MB dye remova...
