“…The solution pH is a crucial factor affecting the adsorption process since it affects both the potential of the adsorbent surface and the form of the adsorbate [39]. As depicted in Figure 5b, the maximum adsorption capacity of 87.3 mg g −1 was attained by PEI−PW@Zr at pH 3, which gradually declined with an increase in pH value.…”

Rapid urban industrialization and agricultural production have led to the discharge of excessive phosphate into aquatic systems, resulting in a rise in water pollution. Therefore, there is an urgent need to explore efficient phosphate removal technologies. Herein, a novel phosphate capture nanocomposite (PEI−PW@Zr) with mild preparation conditions, environmental friendliness, recyclability, and high efficiency has been developed by modifying aminated nanowood with a zirconium (Zr) component. The Zr component imparts the ability to capture phosphate to the PEI−PW@Zr, while the porous structure provides a mass transfer channel, resulting in excellent adsorption efficiency. Additionally, the nanocomposite maintains more than 80% phosphate adsorption efficiency even after ten adsorption–desorption cycles, indicating its recyclability and potential for repeated use. This compressible nanocomposite provides novel insights into the design of efficient phosphate removal cleaners and offers potential approaches for the functionalization of biomass−based composites.

“…Notably, MOFs based on amino acids and their derivatives are widely recognized for their environmental friendliness and biocompatibility. For example, Huang et al [ 94 ] prepared “green” MOFs with aspartic acid derivatives (i.e., spartic acid, succinic acid, fumaric acid, and malic acid) as organic ligands and Zr(IV) as central ions as materials, which are ideal eco-friendly candidates for phosphorus and arsenic(V) removal in complex real water bodies. Moreover, some metals are essential trace metal elements for humans and are not considered toxic for specific applications.…”

Separation is one of the most energy-intensive processes in the chemical industry, and membrane-based separation technology contributes significantly to energy conservation and emission reduction. Additionally, metal-organic framework (MOF) materials have been widely investigated and have been found to have enormous potential in membrane separation due to their uniform pore size and high designability. Notably, pure MOF films and MOF mixed matrix membranes (MMMs) are the core of the “next generation” MOF materials. However, there are some tough issues with MOF-based membranes that affect separation performance. For pure MOF membranes, problems such as framework flexibility, defects, and grain orientation need to be addressed. Meanwhile, there still exist bottlenecks for MMMs such as MOF aggregation, plasticization and aging of the polymer matrix, poor interface compatibility, etc. Herein, corresponding methods are introduced to solve these problems, including inhibiting framework flexibility, regulating synthesis conditions, and enhancing the interaction between MOF and substrate. A series of high-quality MOF-based membranes have been obtained based on these techniques. Overall, these membranes revealed desired separation performance in both gas separation (e.g., CO2, H2, and olefin/paraffin) and liquid separation (e.g., water purification, organic solvent nanofiltration, and chiral separation).

Metal–organic frameworks (MOFs), as porous materials, have been extensively applied in a variety of realms, but little of these has been reported used in sewage disposal field owing to its precariousness toward water. Herein, a novel mixed matrix membrane of polyethersulfone (PES) was synthesized using Cu‐BTC‐IPA, a hydrolytic resistance MOF modified with isopropanol (IPA), which exhibits high permeability and water stability. A significant increase in hydrophilicity of the membrane was found in the modified membranes compared with the pure membrane. The porosity measurement confirmed the increased efficiency of mass transfer in the modified membranes. An enhancement in membrane performance was observed by introducing the Cu‐BTC‐IPA filler into the PES matrix, with a remarkable increase (207%) in pure water flux observed compared to that of the pristine PES membrane (264.2 L m−2 h−1 bar−1), reaching 546.4 L m−2 h−1 bar−1. Meanwhile, it exhibited superior rejection of dyestuffs (98.4% for Congo red and 98.9% for Coomassie brilliant blue). In addition, the Cu‐BTC‐IPA/PES mixed matrix membrane demonstrated remarkable anti‐biofouling properties, as evidenced by its high flux recovery rates of bovine serum albumin (BSA) solutions. The consequences indicate that introducing stable MOF into mixed matrix membranes (MMMs) is extremely effective in improving membrane performance for sewage treatment.
