Abstract ：
Para-arsanilic acid (p-ASA) is widely used as a feed additive, making it a pervasive environmental pollutant. Due to its migratory and transformative nature, p-ASA can easily convert into more toxic inorganic arsenic during its migration, thereby increasing the ecological burden and posing a threat to human health. Efficient removal of p- ASA from water is crucial for mitigating arsenic contamination. Efficient removal of p-ASA from water is crucial for mitigating arsenic contamination. This study introduced zirconium-loaded collagen fiber membrane (CFM-Zr), a novel, sustainable membrane adsorption material synthesized by retanning collagen fiber membranes (CFM) with zirconium (Zr). Leveraging the physicochemical properties of CFM and the strong affinity of Zr forp-ASA, CFM-Zr achieved highly efficient p-ASA removal. The resulting membrane was made entirely from green, low-carbon and recyclable raw materials, achieving sustainable removal of p-ASA while realizing the concept of treating waste with waste for environmental recovery. Remarkably, the retanning with zirconium significantly enhanced the Zeta potential of CFM-Zr, strengthening its electrostatic attraction to p-ASA, with a maximum adsorption capacity of 289.02 mg & sdot;g- 1, which was 19.72 times higher than that of the CFM before retanning (13.95 mg & sdot;g-1). Its adsorption rate constant was 12.54 mg & sdot;g-1 & sdot;min- 1. Moreover, CFM-Zr showed good reusability and exhibited electrostatic adsorption and metal coordination effects on the "organic" parts (-OH,-NH2) and "inorganic" parts (As-O) of p-ASA, effectively removing it. This work provided a promising bio-based material for water purification, promoted the sustainable utilization of leather industry waste, and offered significant advancements in environmental remediation and resource recovery.

Abstract ：
Extracting uranium from seawater has become an important method to supplement the nuclear industry. Herein, we introduce a simple route to load conjugated microporous polymers onto collagen fiber membranes, resulting in a novel membrane adsorbent material (CMPA-F/CFM) for uranium capture. Its Langmuir adsorption capacity reaches 304.9 mg·g−1 (at 318 K), with fast adsorption kinetic of 60 min, and excellent adsorption selectivity with Kd = 4.69 × 104 mL·g−1 under the temperature of 298 K, initial concentration of 50 mg·L-1, and pH = 7, thus allowing a satisfactory adsorption performance in a 7-day real ocean experiment with a uranium adsorption capacity of 1.25 mg·g−1. Furthermore, in continuous dynamic adsorption experiments, CMPA-F/CFM could treat up to 19.0 L·g−1 of low-enriched uranium (LEU) solution (1 mg·L-1), with a uranium removal rate of up to 87.5 % (10 L of seawater). This study demonstrates broad potential application of membrane adsorption in extraction of low-enriched uranium. © 2024 Elsevier Ltd

Abstract ：
China generates over 100 million tons of food waste annually, leading to significant environmental pollution and health risks if not managed properly. Converting FW into a high-value-added platform molecule, lactic acid (LA), through fermentation offers a promising approach for both waste treatment and resource recovery. This paper presents a comprehensive review of recent advancements in LA production from FW, focusing on pure strains fermentation and open fermentation technologies, metabolic mechanisms, and problems in fermentation. It also assesses purification methods, including molecular distillation, adsorption, membrane separation, precipitation, esterification and hydrolysis, solvent extraction, and in-situ separation, analyzing their efficiency, advantages, and disadvantages. However, current research encounters several challenges, including low LA yield, low optical purity of L-(+)-LA, and difficulties in the separation and purification of LA. The integration of in-situ separation technology coupled with multiple separation methods is highlighted as a promising direction for future advancements. © 2024 Elsevier Ltd

Abstract ：
Here, valonia tannin and sulfhydryl functional groups were added to the cellulose aerogel from waste textiles to form a thiol-modified tannin-immobilized cellulose-based aerogel (TVTCA) with selective adsorption and outstanding reducing properties. This aerogel was then utilized to recycle Au(III) in the water. The resulting 3D TVTCA contained abundant-SH groups and phenolic hydroxyl groups and exhibited stable crystal structure and good thermal properties. TVTCA showed excellent Au (III) adsorption performance (598.3 mg/g of maximum adsorption capacity) and strong reductivity (78 %). The adsorption process was conducted using both the pseudo-second-order kinetic model and the Langmuir adsorption isotherm model. In addition, TVTCA displayed excellent anti-interference ability. Even though the coexisting ions concentration was as high as 100 mmol/L, TVTCA still owned a high Au adsorption capacity (178.91-224.14 mg/g) and selectivity factor (29.16-2629.34), which was much higher than valonia tannin-immobilized cellulose-based aerogel (VTCA). Furthermore, the recycling of Au with TVTCA mainly included adsorption and in-situ reduction processes. The mechanisms involved the electrostatic interaction and chelation effects, which were ascribed to the introduced sulfhydryl groups. Meanwhile, the in-situ Au reduction was mainly caused by the studies showing that the high adsorption capacity of TVTCA was owing to the phenolic hydroxyl groups on the introduced valonia tannin. All the findings would provide a new way to achieve the recycling of precious metals from wastewater by using valuable cotton waste.

Abstract ：
As an emerging micropollutant, p-arsanilic acid (p-ASA) would release highly toxic arsenate and arsenite during migration transformation. Herein, a three-dimensional polyethylenimine-aminated leather collagen fiber (CF-PEI) decorated with MgZnFe (MZF) metal oxides, i.e., CF-PEI@MZF monolith, was reported for the ultradeep p-ASA removal. The synergetic functions of hydrogen bonding and electrostatic interaction from the CF-PEI and coordinative interaction from the MZF on the monolith allow an ultrarapid kinetic that could achieve ca. 80% of the adsorption equilibrium within 20 min and a benchmarked exothermic Langmuir adsorption capacity as high as 588.24 mg g(-1) for the p-ASA. It also performed an unparalleled feasibility in the continuous treatment to reduce the concentration of p-ASA to below 0.05 mg L-1 for real applications. We also highlight the monolith structure with great features of easy separation and recycling use for real industrial applications. All these demonstrate the merits of our CF-PEI@MZF monolith in addressing environmental engineering challenges.

Abstract ：
In the wake of the 2011 Fukushima nuclear disaster, the presence of radioactive cesium (Cs-137) in nuclear wastewater has posed a critical and enduring health risk. Addressing this challenge, we have synthesized a gelatin aerogel, denoted as KCuFC/GA, immobilized with potassium cupric ferrocyanide (KCuFC) through an in situ approach, aiming for the efficient extraction of Cs-137 from aqueous environments. This novel aerogel's rich porous structure enhances the accessibility of adsorption sites, thereby significantly promoting the capture of Cs+. The adsorption of cesium onto KCuFC/GA was investigated under various experimental conditions, including initial solution pH, contact time, initial cesium concentration, and the presence of coexisting ions (K+, Na+, Ca2+, Mg2+, Sr2+). The results indicated that the adsorption performance was largely independent of pH, achieving a high cesium removal rate of 93.4 % within the first 5 minutes. The cesium adsorption data were well-described by the Langmuir adsorption model, indicating a maximum adsorption capacity of 222.22 mg center dot L-1. Furthermore, in the presence of various competing ions, KCuFC/GA has demonstrated unparalleled selectivity for Cs+, with a partition coefficient (Kd) of 2.49 x 10(5) mL center dot g(-1), and has sustained its adsorptive properties across five cycles of use. Through systematic investigation, including X-ray photoelectron spectroscopy (XPS) analysis, we have elucidated the adsorption mechanism, highlighting the pivotal role of ion exchange between lattice K+ and Cs+. The straightforward fabrication process and the aerogel's robust cesium removal capabilities from complex solutions indicate that KCuFC/GA is a promising candidate for real-world applications in the treatment of radioactive wastewater.
