“…The macroporous resin relies on the van der Waals force between it and the adsorbed molecules (adsorbents) through their large specific surface area for physical adsorption. Macroporous resin contains many mesh pore structures with microspheres, the total surface area of particles is very large, with a certain polar group, so that macroporous resin has a greater adsorption capacity (dos Santos et al., 2022). The mesh pores have a range of pore sizes, so that they have a certain selectivity to the compound according to the molecular weight.…”

“…According to the polarity, it can also be divided into weak polarity, medium polarity, and strong polarity (Chang et al., 2012). The use of macroporous resin can be divided into static adsorption separation and dynamic adsorption separation according to the operation method (dos Santos et al., 2022, Jia & Lu, 2008, Ke et al., 2021). Static adsorption is to mix the macroporous resin and the treatment solution.…”

“…When all resin adsorption to a certain extent, the adsorption is stopped, and the active ingredients such as flavonoids are eluted with a solvent. Compared with static adsorption, dynamic adsorption has higher adsorption efficiency, and more extracts can be obtained in a single sample loading (dos Santos et al., 2022, Gao et al., 2019, Li et al., 2018, Zhang et al., 2012). It should be noted that macroporous resin needs to be pretreated to remove unpolymerized organic residues.…”

In addition to solute moving toward outer surface of particles, solute molecules can penetrate fine spaces of resin (intragranular diffusion) and interact with available sites on the inner surface of polymeric material (Dos Santos et al, 2022). According to the difference of solid surface adsorption force, it can be (Foo & Hameed, 2010).…”

As a highly selective, recoverable, and low‐cost process, macroporous resins (MPRs) are of interest for the purification of bioactive components from natural products. This guide takes super‐crosslinked MPR as an example, and focuses on application of macroporous adsorption resin in polysaccharide purification, including pretreatment and regeneration of macroporous adsorption resin, various factors affecting the adsorption effect of macroporous adsorption resin, and adsorption mechanism of resin.

Efficient separation of bioactive compounds from nature source, particularly that of astaxanthin (AXT), remains challenging due to their low content in complicated matrix and readily degradable structure. Herein, a modulator‐induced defect engineering is presented on the stable zirconium‐based metal–organic frameworks (Zr‐MOFs) to optimize pore size and pore chemistry for the efficient separation and purification of AXT for the first time. High adsorption capacity of 26.21 mg g−1 is achieved on the best‐performing defect Zr‐MOF (d‐UiO‐67‐4), superior over the other reported adsorbent for AXT. Meanwhile, d‐UiO‐67‐4 exhibits the selective adsorption of AXT over other carotenoids analogues with similar structure and properties. This is attributed to the preferential non‐covalent interactions between defect framework and AXT revealed by the spectroscopy analysis and density functional theory (DFT) calculations. High purity of AXT with 89.0% ± 2.3% extraction efficiency can be realized after the purification of AXT by d‐UiO‐67‐4. The practical separation performance of d‐UiO‐67‐4 for AXT extracted from Haematococcus pluvialis is demonstrated by fixed‐bed column‐based dynamic adsorption and desorption experiments. This work broadens the preparation methods for thermosensitive active substances and provided new research ideas for the controlled adsorption of functional food factors.
