Summary: Increased antibiotic use worldwide has caused concerns due to their health and environmental impacts. This paper reviews the recent progress in using natural and modified clay minerals as efficient and cost-effective adsorbents for the removal of antibiotics from water. The characteristics of clay minerals as adsorbents and the factors affecting the adsorption are explored, along with future trends and strategies to increase their adsorption capacity. The paper also discusses the application of these adsorbents at pilot scale and other related issues such as reuse, economic analysis, and life cycle assessment.

Summary: Benzene adsorption behavior on clay mineral surfaces plays a significant role in its migration and retention in soils. The adsorption mechanisms were investigated through Grand Monte Carlo (GCMC) simulations under various temperatures and air humidity. The results show that benzene forms multiple layers on mineral surfaces, and the temperature has an impedance effect on benzene adsorption due to its temperature-dependent chemical potential. Humidity inhibits benzene adsorption differently due to different surface hydration behavior and competitive adsorption between water and benzene.

Summary: This study focuses on preparing an effective adsorbent for CO2 capture by modifying natural clay with amines. The results show that amine-modified clay can enhance CO2 adsorption capacity, but with lower capacities compared to untreated clay. The Langmuir model fits well with the experimental data, and thermodynamic parameters suggest that the process of CO2 adsorption on amine clay is physical, spontaneous, and exothermic.

Summary: The interaction of organic matter with the mineral components of soil solid phase is crucial for regulating the carbon cycle and balance in the biosphere. The adsorption of fulvic acid and water-extractable organic matter onto kaolinite and muscovite alters the properties and heterogeneity of the organic matter, with hydrophobic components primarily being adsorbed on the mineral surfaces. The adsorption of organic matter is influenced by both the hydrophobic and hydrophilic components, as well as hydrophobic and electrostatic interactions, with different behaviors observed at varying pH levels.

Summary: This paper demonstrates that intercalating Na+ homoionic vermiculite with Fe3+ polyhydroxy cations significantly improves the affinity of the clay mineral-based sorbent toward phosphate. Kinetic experiments show fast adsorption, reaching equilibrium within about 200 minutes of contact time, with intraparticle diffusion being the rate-limiting step. Adsorption isotherms fit well with the Freundlich equation and a two-site Langmuir model, indicating heterogeneity of adsorption sites. The separation factor derived from the Langmuir constant reveals favorable and even irreversible adsorption for high-affinity minor adsorption sites. The adsorption capacity is similar to other clay-based phosphate adsorbents and can remove about 71% of available phosphate in reservoir water spiked with 10 mg L-1 P.

Summary: Operational problems in the oil industry caused by the precipitation of paraffins can be prevented by using polymeric additives. This article evaluates the use of polymeric nanocomposites as pour point reducers in different types of crude oil and finds that they are more efficient than pure poly(ethylene-covinyl acetate) (EVA) in reducing the pour point. The nanocomposites also modify the wax crystals and reduce the viscosity of the oil samples.

Summary: Rutile nano-TiO2 was loaded onto the surface of sericite to prepare sericite-rutile composite particles, which were then modified with HDTMS and sprayed onto the substrates to form sericite-rutile/HDTMS composite coatings with UV shielding and superhydrophobic self-cleaning properties. The coating exhibited good UV shielding rate and remained superhydrophobic after UV irradiation. The hierarchical structure of the sericite-rutile composite and the low surface energy of HDTMS contributed to the superhydrophobicity and UV shielding effect of the coating.

Summary: Environmental conditions significantly influence clay minerals, and studying clay sediments in tropical lakes can provide valuable insights into past environmental conditions. In this study, multiproxy records from sediment cores of three crater lakes in central Mexico were analyzed. The results showed that disordered kaolinite, formed through hydrolysis and hydrothermal alteration, was the predominant mineral in the sediments. The abundance of kaolinite varied in relation to organic carbon and organic matter-related elements, and showed opposite trends with lithogenic elements. Geochemical data suggested that the increase in kaolinite abundance is linked to the formation of organo-mineral aggregates and lake level changes in closed basins.

Summary: The interaction between talc and the depressor CMC was investigated through molecular dynamics simulation and density functional theory calculation. It was found that CMC showed stronger adsorption on the edge plane of talc due to enhanced interactions with polar groups and water molecules. The study also revealed specific interactions between H atoms in CMC and O atoms in the edge plane, as well as between O atoms in CMC and Si, Mg atoms in the edge plane. Hydration shells on the basal and edge planes of talc were examined to explain the phenomenon.
