“…Therefore, the adsorption performance of the macroporous resins in terms of flavonoids was associated with the synergistic effects of their chemical compositions and physical properties (Lv et al 2018). The selected resins with larger specific surface areas possessed a slightly stronger desorption capacity than the other three resins, which suggested that the specific surface area might be one of the critical factors that affect the desorption process (Scordino et al 2003).…”

“…where Qe is the adsorption capacity at equilibrium (mg/g of dry resin), D is the desorption ratio (%), C0 is the initial flavonoid content in the solutions (mg/mL), Ce is the flavonoid content in the solutions at equilibrium (mg/mL), Vi is the initial sample solution volume (mL), W is the dry resin weight (g), Cd is the flavonoid content in the desorption solution (mg/mL), and Vd is the desorption solution volume (mL) (Yang et al 2016;Lv et al 2018).…”

“…The fitting equations and kinetic parameters at 25 °C and correlation coefficients of the pseudo-firstorder and pseudo-second-order kinetic models and particle diffusion were calculated and listed in Table 2. In the kinetic experiment, the pseudo-first-order model was primarily used to describe the initial stage of adsorption, while the second-order equation was used to predict the adsorption behavior of the entire adsorption process (Lv et al 2018). It was found that the pseudo-second-order kinetic model was better at depicting the kinetics of the adsorption of flavonoids onto resins, The coefficient of determination (R 2 ) of the pseudo second-order model was greater than that of the pseudo first-order model, which meant the pseudo second-order model had a better linear correlation with the adsorption kinetics, and the theoretical Qe values estimated from the pseudo-second-order kinetic model were close to the measured results.…”

“…It also confirmed that temperature is a key factor affecting the amount of adsorption. Higher temperatures may accelerate the frequency of thermal motion of the molecules in the solution, thereby reducing the interaction between the target compound and the active sites on the resin, leading to a reduction in the amount of adsorption (Lv et al 2018). From the analysis results, it can be found that the Langmuir model had a good coefficient of determination at different temperatures compared with other models, which means that it can be used as a good adsorption model to reflect the adsorption equilibrium of the selected resins in terms of flavonoids.…”

“…Therefore, kinetic data could be fit to kinetic models (pseudo-first-order kinetics and pseudo-second-order kinetics models) to clarify the type of adsorption (Yang et al 2016). Adsorption isotherm models, e.g., Langmuir or Freundlich, were chosen to speculate on the adsorption mechanisms, and additional thermodynamic parameters, i.e., enthalpy change, entropy change, and free energy, can be derived (Lv et al 2018).…”

The adsorption and desorption properties of 12 resins containing flavonoid compounds found in Eucommia ulmoides Oliv. leaves (EUOL) extracts were investigated. The static adsorption and desorption, kinetic, adsorption, and thermodynamic properties of the adsorption of the flavonoids onto macroporous resins were determined. The HPD-300, NKA-9, and AB-8 resins exhibited a greater adsorption capacity and desorption characteristics. A pseudo-second-order kinetic model was suitable to characterize the kinetics of the adsorption of flavonoids onto the resins selected, and the diffusion of flavonoids was divided into three stages, with the boundary layer diffusion and intra-particle diffusion being the rate-controlling factors. The Langmuir model was found to be the best description of the adsorption behavior of flavonoids. Thermodynamic studies indicated that the adsorption of flavonoids was a physical, exothermic, and spontaneous process. The 60% ethanol eluted fraction from the NKA-9 resin column not only had the highest flavonoid content, but also possessed the strongest inhibitory effect on acetylcholinesterase. In addition, the degree of binding of the main flavonoid compounds found in the EUOL to acetylcholinesterase compounds was investigated via molecular docking technology. The results showed that the docking total score of isoquercetin and enzyme proteins were the highest, followed by kaempferol-3-O-rutinoside.

UV–Vis spectrophotometry has been widely applied in the quantitative analysis of different analytes in many fields, but it still faces challenges in the analysis of multicomponent solutions due to strong spectral overlap and low selectivity. In this paper, UV–Vis spectrophotometric method combined with chemometrics algorithms was established for the simultaneous determination of liquid‐phase adsorption kinetics of multicomponent for the first time. Partial least squares (PLS), stepwise regression, and multiway PLS (N‐PLS) models were established by using the original spectrum and processed spectrum pretreated by two different methods. The prediction results were validated by high‐performance liquid chromatography (HPLC). N‐PLS model showed the best prediction ability and the prediction relative error was within 9%. Adsorption kinetics studies indicated that the pseudo‐second‐order model can describe the adsorption behavior of rutin and quercetin on AB‐8 resin more accurately. This method was fast, low cost, accurate and reliable, simple, and efficient for the determination of multicomponent liquid‐phase adsorption kinetics.

Density functional theory (DFT) was used to explore the possibility of h-BN monolayer acting as an adsorbent for the flavonoids. Four flavonoids named apigenin, kaempferol, myricetin, and quercetin as well as glucose (Glu) were selected as representatives of honey. DFT and ab initio molecular dynamics simulation results show that the four flavonoids interact with the h-BN monolayer much stronger than the Glu does in both vacuum and solutions, indicating a good adsorptive selectivity of the flavonoids over Glu. The interaction of the flavonoids and the Glu with water as well as the solvation energy of the flavonoids in water, methanol and ethanol was obtained using both the PBE-D and B3LYP-D functionals. It is shown that the h-BN monolayer can provide high selective adsorption of the flavonoids from bee honey and ethanol can be used as an elution solvent to recover the adsorbed flavonoids.
