“…As shown in Table 2, according to the R 2 , the adsorption of BY28 molecules on the synthesized samples wellfitted with the Langmuir model indicating the establishment of monolayer coverage of the BY28 molecules on the outer and inner surfaces of the adsorbents. This also refers that the competition of the solvent and the adsorbate to attach the adsorbent sites is not strong and indicates the high efficiency of synthesized samples to adsorb BY28 dye [76]. The indium-incorporated samples, IM0.05 and IM0.1 showed higher BY28 adsorbing capacity (156.99 and 158.48 mg g -1 , respectively) in comparison with the pure sample (123.46 mg g -1 ).…”

Highly ordered pure MCM-41 and In-MCM-41 mesoporous adsorbents (with Si/In = 95 (IM0.05) and Si/In = 90 (IM0.1)) were synthesized using the hydrothermal-assisted method. The structural, morphological and texture characteristics were investigated by XRD, N2 adsorption–desorption, SEM-EDX, TEM, diffuse reflectance (DR) and FTIR. The broadening XRD diffraction peaks as well as the shifts to higher and lower 2-theta in IM0.05 and IM0.1, respectively, confirmed the incorporation of indium atoms in the MCM-41 structure. SEM-EXD and TEM images showed that pure MCM-41 and IM0.05 preserve a highly long-range well-ordered hexagonal pore structure, on the other hand, high loading of indium (IM0.1) resulted in partially irregular pore-ordering and morphological defects related to a partial dissolution of MCM-41 structure. The infrared spectra of In-incorporated samples showed a decrease in the transmittance intensity of MCM-41 characteristic peaks with little shifts relative to the pure MCM-41 sample. The potential of pure MCM-41 and In-MCM-41 samples for adsorption of dyes was preliminarily investigated. The removal efficiency of both methylene blue and basic yellow-28 (BY28) was enhanced by the incorporation of indium in the MCM-41. The adsorption equilibrium data of BY28 dye on pure, IM0.05 and IM0.1 samples fitted well with Langmuir adsorption model with adsorption capacity of 123.46, 156.99 and 158.48 mg g−1 respectively. The calculated free adsorption energy obtained from D–R isotherm was found to be 26.7 kJ mol−1 referring to that the adsorption of BY28 on IM0.05 adsorbent is chemical. The adsorption kinetic of BY28 on IM0.05 sample followed the pseudo-second-order model. The adsorption experiments revealed that the prepared samples can be used as effective adsorbents for the removal of dyes in aqueous solutions with good recovery and recyclability.

“…Where, q e (mg•g −1 ) was the adsorption capacity at BSA adsorption equilibrium, C e (mg•l −1 ) was adsorption equilibrium concentration of BSA, K F was the equilibrium constant of Freundlich isothermal model. The parameter 1/n of Freundlich isothermal model was 0.6382 which was between 0 and 1, indicating that the adsorption of BSA onto magnetic α-Fe 2 O 3 nanoparticles was favorable [45,49].…”

“…But the removal rate had no significant change when the dosage of adsorbent increased from 2.5 mg•l −1 to 4 mg•l −1 . The reason was that the adsorption sites overlap with the increase of magnetic α-Fe 2 O 3 nanoparticles dose, limiting the adsorption capacity of the surface [45]. Hence, the optimal dosage of magnetic α-Fe 2 O 3 nanoparticles for BSA adsorption was 2.5 mg•l −1 .…”

The assumption of Freundlich isothermal model was that multimolecular layer adsorption occurred on heterogeneous surfaces [45]. The formula of Freundlich isothermal model was formula (6).…”

The α-Fe2O3 nanoparticles were prepared via the alcohol solution combustion process of ferric nitrate. The scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS). X-ray diffraction (XRD), and vibrating sample magnetometer (VSM) were taken to characterize the prepared α-Fe2O3 nanoparticles. The average particle sizes of the as-prepared α-Fe2O3 nanoparticles were approximately 180 nm, and their magnetic property was approximately 0.42 emu·g-1 after the measurement. The different concentrations of BSA solutions and the adsorption times were investigated to investigate the adsorption characteristics of bovine serum albumin (BSA) onto α-Fe2O3 nanoparticles. For larger adsorption capacity and higher removal rate, the dose of α-Fe2O3 nanoparticles in aqueous solution was selected at 2.5 mg·mL-1. The adsorption process of BSA onto α-Fe2O3 nanoparticles conformed to the pseudo-first-order kinetic model. While, the correlation coefficient (R2) of the Temkin isothermal model was higher than Langmuir model and Freundlich isothermal model, suggesting that the isothermal model of BSA onto α-Fe2O3 nanoparticles was more in line with Temkin isotherm model. Which suggested that the adsorption behavior of magnetic α-Fe2O3 nanoparticles for BSA belonged to multi-molecular layer chemisorption. When BSA concentration was 600 mg·L-1 and the pH of solution was 5, the adsorption capacity of BSA onto magnetic α-Fe2O3 nanoparticles achieved 114.2 mg·g-1, and the adsorption rate could still reach 70.3% of the first time after 7 cycles.
