Summary: The transformations of monovalent thallium (Tl) in an aqueous environment are significantly affected by Tl(I) partitioning at the solid-water interface during sorption. Two unified adsorption models, diffuse layer modeling and kinetics modeling, accurately predict the environmental fate of thallium by quantifying the kinetics of Tl (I) adsorption on heterogeneous adsorbents and the formation of multiple complexes under a wide range of water chemistry conditions. The characteristics of different Tl(I) complexes have influence on the adsorption and desorption processes.

Summary: This study analyzes the pore structure and methane adsorption characteristics of Wufeng and Longmaxi shales through nitrogen physical adsorption and methane isothermal adsorption, providing insights into the methane adsorption mechanism in gas reservoirs. High pressure promotes methane adsorption on shale while high temperature reduces adsorption capacity. The effect of pressure on adsorption is greater than that of temperature, and increasing pressure decreases adsorption potential.

Summary: In this study, the temporal changes in pools of arsenic (As) and lead (Pb) in sediment amended with biochars produced from sugarcane pyrolyzed at different temperatures were evaluated. It was found that over time, biochar was effective in reducing the bioavailable and exchangeable forms of As and Pb. The study highlights the important role of biochar in immobilizing and reducing the contents of potentially toxic elements in contaminated sediments.

Summary: The removal or immobilization of PFASs from water or soil using carbon-based sorbents is a cost-effective technique. This study evaluated the performance of 28 carbon-based sorbents and found that PAC, mixed mode carbon mineral material, and GAC were the most effective in sorbing PFASs. Surface area and surface charge were identified as the best indicators of sorbent performance for PFASs removal or immobilization.

Summary: By using statistical thermodynamic fluctuation theory, the sorption mechanism can be elucidated directly from an experimental isotherm without the need of using an isotherm model. The key to understanding the sorption mechanism lies in how sorbate-sorbate interaction depends on activity, without assuming adsorption sites and planar layers.

Summary: This study focused on the design of a new decolorization agent by immobilizing Mucor plumbeus cells on sepiolite matrix. The immobilized material showed high decolorization performance for methyl violet, with Langmuir isotherm model and pseudo-second-order kinetics being the best-fitted models. The sorption reaction was found to be exothermic with an increase in entropy, and the fixed bed column exhibited almost 100% decolorization yield.

Summary: The hydration process of a Nafion membrane was studied using ambient-pressure x-ray photoelectron spectroscopy (APXPS), which provided a quantitative analysis of water content and the transformation of sulfonic acid groups. The conductivity of the membrane was determined by electrochemical impedance spectroscopy, establishing a connection between the electrical properties and the microscopic mechanism. Ab initio molecular dynamics simulations provided core-level binding energies of O- and S-containing species in the Nafion + H2O system.

Summary: The sorption calorimetry method developed by Wadso and co-workers is successful in measuring both water sorption isotherm and sorption enthalpy, though accuracy can be affected by diffusion. A new calculation method is proposed to eliminate these effects and improve the accuracy of enthalpy measurements. This new method has been successfully tested on previously published data and can be recommended for future experiments.

Summary: Two novel reaction-based ratiometric fluorescence probes (Phe-HBT and Me-HBT) were reported for the selective and sensitive detection of N2H4. The detection of N2H4 at low levels could be visualized by naked eyes under daylight or UV light with a fast response time of about 8.0 min for Phe-HBT and 16.0 min for Me-HBT. Both probes showed high specificities for N2H4 among potential competing analytes, and were successfully applied to detect aqueous trace N2H4 in various samples. The detection of N2H4 was also tested using smartphone application and modified fabric, demonstrating its potential value in practical applications.
