Operative utilization of the feasible anion exchange membrane BIII for Sorptive exclusion of acid orange 7 from Hydrated media

Anion exchange membranes have received great deal of attention for their ability to remove harmful dye contamination from industrial wastewater while also ensuring profitable and fuel-efficient commercialization. The ability of anion exchange membrane BIII to eradicate acid orange 7 dye from aquatic environment is demonstrated here. SEM and FTIR analyses revealed the surface properties and existence of distinct operational groups on the sorbent. Numerous constraints on AO7exclusion in an aquatic environment, such as contact duration, temperature, sorbent dose, and starting dye concentration were also scrutinized. For the purpose of assessing kinetics, Liquid film diffusion, Elovich, Lagergren first-order, Bangham, pseudo-second-order, and modified Freundlich models, were employed. These findings imply that the AO7 dye sorption onto the BIII membrane is well controlled by the liquid-film diffusion process and that the sorption comprehends pseudo-second-order kinetics with an utmost value of R2(0.99). To evaluate tentative data, multiple linear and nonlinear isotherm models were utilized. Freundlich isotherm was found to be in excellent agreement with sorption data. Thermodynamic specifications, such as a change in Gibb's free energy, enthalpy, and entropy, for dye sorption on the anion exchange BIII membrane were optimized between 308 and 338 K to maximize AO7 dye removal. Since ΔGo is negative and, ΔHo and ΔSo are positive, inferred that the sorption is spontaneous and endothermic. Anion exchange membrane BIII was effective for up to four successive cycles without losing its competence.
