“…Adsorption Removal of MB: The MCA (0.1 g) was placed into a 22.5 ml (5.6 mg l -1 ) MB solution. NaOH (0.2 mol l -1 ) and HCl (0.2 mol l -1 ) were employed for adjusting the initial pH (3,7,9,12) of mixed solution. UV-vis absorption measurements were investigated by evaluating the concentration changes of the MB solution before and after treatment at a maximum absorption band of 664 nm.…”

There are many ways including chemical coagulation, ozone oxidation, photocatalytic degradation and adsorption [3][4][5][6] to remove organic pollutants from contaminated water. Among them, adsorption is the currently advocated technique for organic pollutants from wastewater in terms of high efficiency and excellent applicability. [7,8] However, the potential drawback of this method is that it will leave undesirable by-products and adsorbed precipitants in the environment. This has been addressed by using magnetic carriers, which can be collected by an external magnetic field. [9,10] Therefore, the magnetic adsorption strategy is the most promising method for removing organic pollutants.Because of abundant chemical groups and a substantial porous structure, aerogel is accepted as an effective adsorbent for removing hazardous pollutants. Li et al. [11] have developed a woodinspired nanocellulose aerogel adsorbent with excellent selective capability, superfast adsorption, and easy regeneration. Guo et al. [12] have designed a cellulose nanofiber (CNF) framework to form an eco-friendly and low-cost microporous aerogel to capture Cu(II) and organic contamination. In recent years, cellulose has become an intriguing host due to its excellent characteristics, such as high specific surface area, high aspect ratio, well chemical stability, and natural biodegradability. [13][14][15] Hu et al. [16] have reported that an effective strategy to transform bulk cellulose directly into a high-performance structural material by hot-pressing. Li et al. [17] have obtained a printed, recyclable, ultra-strong, and ultra-tough graphite structural material with high tensile strength (up to 1.0 GPa) and toughness (up to 30.0 MJ m −3 ). They can not only provide a natural skeleton for assembling a 3D network structure but also offer a large amount of surface hydroxyl groups for various treatments with the aim of improving its functionalities and performances. [14,[18][19][20] Meanwhile, the Fe 3 O 4 nanoparticles are highly promising nanomaterials in the fields of catalyst support, [21] oil-water separation, [22] and information storage [23] on account of evident advantages, such as high specific surface area, chemical stability, simple extraction, and nontoxicity. More importantly, relatively complex magnetic materials are applied for organic 3D printing of biomass has attracted increasing attention and can meet the requirements of various practical applications. Herein, 3D printing of a cellulose-based aerogel is achieved by direct ink writing based on a selfthickening and self-strengthening strategy, followed by freezing drying. The magnetic cellulose-based aerogels (MCAs) containing Fe 3 O 4 nanoparticles are ideal adsorbents for adsorbing and removing organic pollutants from water. As catchers and carriers for magnetic removal, MCAs (Fe 3 O 4 nanoparticles and cellulose) provide large active sites, which allows organic pollution to be quickly and stably bound on the surface. The adsorption effect of methylene blue (MB) is dependent ...

“…Additionally, some nanomaterials exhibit highly reactive surfaces that can be functionalised for catalysing the degradation of the adsorbed pollutants. [7,8] Researchers have recently begun to develop supramolecular strategies based on host-guest chemistry to capture and separate substances of interest. [9][10][11][12] In these strategies, discrete molecular compounds can be used in solution to selectively recognise, adsorb, and entrap the substance of interest inside their cavities.…”

Water pollution threatens human and environmental health worldwide. Thus, there is a pressing need for new approaches to water purification. Herein, we report a novel supramolecular strategy based on the use of a metalorganic polyhedron (MOP) as a capture agent to remove nitrogenous organic micropollutants from water, even at very low concentrations (ppm), based exclusively on coordination chemistry at the external surface of the MOP. Specifically, we exploit the exohedral coordination positions of Rh II -MOP to coordinatively sequester pollutants bearing N-donor atoms in aqueous solution, and then harness their exposed surface carboxyl groups to control their aqueous solubility through acid/base reactions. We validated this approach for removal of benzotriazole, benzothiazole, isoquinoline, and 1-napthylamine from water.
