Summary: A novel high-efficiency vermiculite/zinc hexacyanoferrate (II) (VMT/ZnHCF) composite adsorbent was prepared to solve the problems of low adsorption capacity, complex preparation, and difficult recovery for reported cesium ion adsorbents. The composite exhibited a maximum Cs+ adsorption capacity of 378.79 mg/g, which was significantly higher than other absorbents. The Cs+ adsorption mechanism was revealed to be synergistically achieved through the ion exchange of Na+ in vermiculite interlayers and Zn2+ in zinc hexacyanoferrate (II) lattices, as analyzed by ion exchange experiments and characterization techniques.

Summary: The use of mineral clays as alternative adsorbent has been explored due to their physicochemical characteristics and low cost. In this study, expanded vermiculite and sodium-modified vermiculite were evaluated for their adsorption capacity and ion exchange of Cd2+ ions. The sodification process successfully increased the ion exchange capacity of the modified clay, resulting in higher adsorptive capacity and faster kinetics for Cd2+ removal. Despite the decrease in surface area after sodification, the modified adsorbent showed a significant increase in adsorptive capacity.

Summary: Run-of-mine (ROM) palygorskite from Guadalupes in Piaui, Brazil, was found to have a maximum sorption capacity of 18 mg/g for Nd3+ ions. More than 99% of Nd was removed from the solution at pH 5. The Temkin model provided the best fit for the sorption data, indicating an electrostatic interaction between PAL and Nd3+ ions.

Summary: This study presents a reactive transport model for the in-situ recovery of weathered crust elution-deposited rare earth ores and validates the model through various experiments. The results show that using a single selection coefficient for modeling is acceptable and that Darcy velocity and leaching solution concentration have significant effects on the leaching process. Optimal cessation of leaching solution injection can conserve solution and reduce pollution. The differences in parameters derived from different experiments highlight the need for further investigation.

Summary: In this study, vermiculite was used as an adsorbent to remove methylene blue dye. Experimental results showed that the adsorption capacity of vermiculite increased with increasing initial dye concentration, but decreased with increasing adsorbent dosage. Factors such as temperature and initial pH had little effect on the adsorption capacity.

Summary: The demand for rare earth elements (REEs) has been increased by contemporary industrial processes and the application of new technologies. However, the increased mining of REEs has led to a supply crisis. Researchers have recently started considering the viability of recovering REEs from secondary sources such as mining wastewaters and acid mine drainage. In order to find more sustainable processes, the performance of various adsorption/ion exchange materials in capturing REEs from water sources is being evaluated.

Summary: This study investigated the removal of Ethidium bromide (EtBr) from aqueous solutions using a naturally occurring palygorskite (PFl-1) clay mineral. The results showed that EtBr was adsorbed on PFl-1 mainly through a cation exchange-based adsorption mechanism, with increased removal efficiency at higher adsorbate concentrations. PFl-1 was found to be a promising natural material for removing EtBr from pharmaceutical and laboratory wastewater.

Summary: By analyzing the mineralogical and geochemical characteristics of the mudstone, the study clarified the manner by which the palygorskite evolved and concluded that it was generated from the dissolution of detrital clay minerals. The REE and enriched trace elements in the authigenic palygorskite were inherited from the detrital clay minerals.

Summary: In this study, a cation exchange resin (HIAO/225H) containing hydrated iron-alum oxides was synthesized from natural alum-ferric water of acid sulfate soil to improve water quality. The HIAO/225H material exhibited high adsorption capacity for phosphate and hardness removal, outperforming other materials under the same experimental conditions. The presence of Ca, Mg, and Al elements in HIAO may contribute to its superior phosphate adsorption efficiency. The results suggest that HIAO/225H could be an effective material for water and wastewater treatment applications.

Summary: A class of robust charge-selective membranes, consisting of monolayer nanosheets with inherent surface charges, have been reported. These membranes exhibit superhigh cation/anion selectivity, outperforming previously reported ion-selective membranes. They maintain excellent ion selectivity even in high-concentration salt solutions, acidic and alkaline conditions, and for a wide range of ions of different sizes and charges. By coupling cation-selective and anion-selective membranes, a reverse electrodialysis device with high energy conversion efficiency has been constructed. This work provides a new strategy for designing high-performance ion-selective membranes using 2D nanosheets.

Summary: The study found that high-fructose, high-fat diets may lead to an increase in total triacylglycerol content in muscle tissue, but a decrease in intramyocellular lipid content and the number of type I (slow oxidative) muscle fibers. Additionally, high-fructose, high-fat diets also induced autophagy and inflammation responses.
