“…This agrees well with the theoretical observation that the adsorption sites of CDPU interact with CAc stronger than CA. Three kinetic models, that are, the pseudo-rst-order, pseudo-second-order and intra-particle diffusion models as shown in eqn (5)- (7), 37 were employed to explore the adsorption kinetic behavior.…”

In order to isolate cinnamyl acetate (CAc) and cinnamaldehyde (CA), which coexist in cinnamon oil, a crosslinked polymer of b-cyclodextrin polyurethane (CDPU) was synthesized via a facile route and investigated as a selective adsorbent. The successful crosslinking was confirmed by FTIR, TG-DSC, XRD, SEM and N 2 adsorption-desorption analysis. The adsorption mechanism was investigated through a series of instrumental analyses and theoretical calculations, indicating that the combination of noncovalent interactions (e.g., hydrogen bonding, hydrophobic interactions) accounts for the superior affinity of CAc to CDPU, compared with CA. The adsorption behaviors of CAc and CA on CDPU were performed in the static adsorption mode, in which CDPU exhibited a selective adsorption property to CAc. The adsorption kinetics and isotherms in a single component system agreed well with the pseudosecond-order kinetic model and Freundlich isotherm model, respectively. It is noteworthy that the equilibrium adsorption amount was enhanced in the presence of the co-solute, presumably resulting from the cooperative effect arising from Lewis acid-base and p-p stacking interactions between the adsorbed CAc and CA molecules. Due to the stronger adsorption affinity of CAc to CDPU, adsorption enhancement of CAc in the presence of CA is greater than that of CA in the presence of CAc, resulting in higher CAc/CA selectivity with increasing concentrations of the equimolar mixture of CAc and CA.Additionally, CDPU could be easily regenerated and maintained high adsorption capacities and separation efficiency even after six adsorption/desorption cycles.

“…In continuation to our prior works [40][41][42][43][44][45] , we have synthesized modified magnetic Fe 3 O 4 @SiO 2 -TRIS NPs by the steps shown in Figure 1. First, Fe 3 O 4 NPs were prepared by the co-precipitation of Fe 2+ and Fe 3+ ions in a basic solution.…”

“…[59] The calculated isotherm parameters of two anionic dyes from both models are shown in Table 2. [60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79] Though Fe 3 O 4 @SiO 2 -TRIS has a large number of terminal hydroxyl groups, their maximum dye binding capacity is less than that of Fe 3 O 4 @SiO 2 -MPAP [41] and Fe 3 O 4 @SiO 2 -NH 2. It indicates that the adsorption occurs at specific homogeneous sites within the adsorbent, forming a monolayer coating of the dye at the surface of the adsorbent.…”

“…TEM analyses reveal that the presence of SiO 2 and TRIS shell increase the size of the magnetite NPs. [41] In the inset of Figure 3b, the XRD patterns of Fe 3 O 4 @-SiO 2 -TRIS NPs are shown, with sharp diffraction peaks at 2θ = 30.4 (220), 35.5 (311), 43.4 (400), 53.8 (422), 57.3 (511), and 62.6 (440), which indicates that the Fe 3 O 4 @SiO 2 -TRIS particles have highly crystalline cubic spinel structure of magnetite. The average crystallite size (D) was determined by the Scherrer formula, D = Kλ/(βcos θ), where λ = 1.54 Å is the wavelength of the Cu Kα radiation used, β is the full width at half-maximum (FWHM) intensity of the diffraction line, θ is the Bragg angle for the measured hkl peak (Miller indices), and K is a constant equal to 0.94.…”

The adsorption of the dyes Acid Red 114 and Reactive Black 5 in aqueous solutions on polyhydroxyl dendrimer magnetic nanoparticles (Fe3O4@SiO2‐TRIS) was studied in a batch system. The Fe3O4@SiO2‐TRIS NPs were characterized by Fourier transform infrared spectroscopy, X‐ray diffraction, and transmission electron microscopy. Experiments were performed under different conditions such as the initial dye concentration, adsorbent dose, and pH. The pseudo‐second‐order model provided a very good fit for the two anionic dyes. The Langmuir and Freundlich adsorption models were used to describe the equilibrium isotherms at different temperatures, and the former agreed very well with the experimental data. However, the adsorption capacity of Fe3O4@SiO2‐TRIS NPs was reduced during surface modification, which could be due to the dye occupying the binding sites of the dendrimer. Thermodynamic parameters, namely the change in free energy (ΔG0), enthalpy (ΔH0), and entropy (ΔS0), were also determined.

“…In order to elucidate the mechanism of high removal ability of MCMP, pseudo‐first‐order and pseudo‐second‐order models were used to simulate the adsorption kinetics of MCMP in different initial dye concentrations. The models are given by the following Eqns (2) and (3) and the kinetic parameters for the MCMP shown in Table . K 1 and K 2 are the rate constants of the adsorption kinetics model, respectively, and q e is the amount of adsorption equilibrium; both could be obtained from the intercept and slope.…”

BACKGROUND A magnetic conjugated microporous polymer (MCMP) composite was designed with bromo groups of CMP and amino groups on the surface of Fe3O4 nanoparticles that acted as promising adsorbents for wastewater treatment. Fe3O4 nanoparticles were successfully bonded on the predesigned CMP material to form the MCMP by means of a new and simple nucleophilic substitution reaction in organic media. RESULTS The MCMP could be separated by applying an external magnetic field because of the Fe3O4 nanoparticles. It exhibited sufficient dye adsorption for methylene blue (MB) with a high sorption capability of 869.43 mg g−1 in aqueous solutions. The recovery and reusability of MCMP were >70% after six cycles of desorption and regeneration, indicating that the MCMP had excellent cycle stability. The magnetization saturation strength of MCMP was 13.5 emu g−1 which was sufficient to be magnetically separated from wastewater using artificial magnetic fields. CONCLUSION The MCMP possessed excellent adsorption capacity and dispersibility, and good recyclability after banded with functionalized Fe3O4 nanoparticles. The excellent properties of MCMP indicated that it could be used as an adsorbent with great application potential for quick separation of water pollutants such as dyes in wastewater treatment. © 2019 Society of Chemical Industry
