Summary: This study developed a method to determine adsorption parameters for potentially contaminant-releasing materials (PCMs) using LS-parallel tests, which showed good agreements for some substances but discrepancies for others. Improvement is needed in the LS-parallel test procedure and advection-dispersion model for accurate prediction of contaminant release behavior.

Summary: This study systematically investigates the high-temperature carbon capture process using Li4SiO4-based solid adsorbent. The equilibrium boundary and thermodynamic parameters of the Li4SiO4-CO2 reaction system were calculated, providing an empirical formula for practical equilibrium temperature. The CO2 adsorption and desorption processes were analyzed kinetically and thermodynamically, and the key parameters of Li4SiO4 within 10 ad-desorption cycles were calculated.

Summary: This study quantifies the contributions of adsorption, bioreduction, and desorption in EPS-mediated U(VI) immobilization. Experimental results show that U(VI) immobilization is faster when exposed to H-2 compared to O-2. The kinetic model reveals that adsorption is dominant in the first minute, bioreduction is dominant from the second minute to the 50th minute, and after 50 minutes, bioreduction is balanced by desorption. This study also provides the first set of equilibrium data for U(VI) adsorption by EPS alone and shows that U(VI) adsorption onto EPS is endothermic, spontaneous, and favorable at higher temperatures.

Summary: Research indicates that the equilibrium temperature for CO2 adsorption/desorption of Li4SiO4-based sorbents at high temperatures is higher than theoretical values, with silicon precursors and Ce/Fe dopants having minimal effects on equilibrium. Sorbents with K/Na exhibit significant drops in equilibrium temperature at 0.5 atm of CO2, and higher K doping results in lower turnover temperatures.

Summary: Adsorptive separation techniques are more energy efficient than conventional thermal separation techniques such as distillation. However, the use of adsorption techniques for the separation of multicomponent liquid mixtures is still limited due to the lack of accurate adsorption thermodynamic models. In this study, the surface excess of adsorption for six binary liquid mixtures on silica gel was rigorously computed using the frameworks of the generalized Langmuir isotherm and the adsorbed solution theory.

Summary: As phenolic acids accumulated in monocropping plantations, their allelopathic effects caused the decline in soil fertility and decrease in productivity. The effects of stand age and generational turnover of phenolic acids in soil were examined through an experiment. The study found that soil from the 6-year-old first-generation plantation had the highest accumulation of phenolic acids, and p-hydroxybenzoic acid may have the highest allelopathic capacity in these Eucalyptus plantation soils. The adsorption and desorption rates and amounts of phenolic acids were also higher in the 6-year-old first-generation plantation soil compared to other soils.

Summary: This study characterized the plant available zinc at different landscape positions by conducting adsorption-desorption studies on soil samples collected from on-farm trials in Ethiopia. The amount of adsorption and desorption was found to be highly associated with soil pH, organic carbon concentration, and cation exchange capacity, with Freundlich and Langmuir isotherm models fitting well to the data. Multiple regression models were developed to inform zinc fertilizer management strategies for improving plant zinc use efficiency in different locations and landscape positions in the region.

Summary: Triboelectrochemical reactions occur on solid-liquid interfaces when a strong enough electric field and sufficient frictional stress are simultaneously imposed. These reactions are influenced not only by thermal energy, but also by electrical and mechanical energies, which in turn affect the properties of the interfaces.

Summary: The study showed that the metabolite ESA-metolachlor had a significant inhibitory effect on denitrification, while propiconazole and 1,2,4-triazole had a smaller impact. Pesticides affected the nitrate reduction process but did not significantly alter the abundance of nitrate reductase genes. Overall, pesticides and metabolites at environmental concentrations can have side effects on microbial denitrification and potentially impact ecosystem services.

Summary: Nitrate contamination of groundwater is a major concern despite efforts to protect water resources. Research in a Brittany catchment revealed heterogeneous nitrate concentrations influenced by geological structures and weathering layers. A combined approach of geology, geochemistry, isotopic methods, microbiology, geophysics, and hydrogeology is crucial for effective measures and assessing their impact on groundwater quality.

Summary: Although multielement isotope fractionation studies have been well-established for point-source pollution, they are only emerging for diffuse pollution by micropollutants like pesticides. This study found that chlorine isotope fractionation can be a robust indicator of chloroacetanilide degradation, with distinct patterns observed for different degradation pathways. The 3D isotope approach allows for differentiation of transformations that may not be distinguishable based on C and N isotope data alone.

Summary: Preserving or restoring the quality of groundwater resources in terms of nitrate is a challenging task. However, there is a lack of useful and easily applicable tools to identify the best measures to implement at the local level. In this study, an innovative methodology combining a model simulating nitrate groundwater contamination time series and economic evaluation was used to identify cost-effective restoration measures at a drinking water catchment scale. The study was conducted in a representative catchment in Northwest France that has been affected by nitrate contamination for several decades. The results show that significant changes in cropping patterns are needed to achieve the long-term goal of restoring groundwater quality targets.
