Summary: The present study successfully designed a novel porous Zn/Fe LDH adsorbent using a combination of co-precipitation, hydrothermal, and thermal treatment methods. Intercalating H2O2 into LDH followed by thermal treatment created pores in the LDH layers, leading to increased surface area. The synthesized adsorbent showed a high adsorption capacity for the antibiotic ciprofloxacin, following Freundlich isotherm model and pseudo-second-order kinetic model, with C pi-metal interactions, hydrogen bonding, and electrostatic interactions playing major roles.

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: This study investigated the inactivation of bacteriophage MS2 under irradiation above 320 nm, considering different solution pH, ionic strength, and Suwannee River natural organic matter (SRNOM) concentrations, as well as the presence of organic or inorganic particles. The results showed that the presence of kaolinite and Microcystis aeruginosa particles influenced the inactivation rate of MS2 under different conditions. The lower pH and the presence of reactive oxygen species (ROS) induced by particles promoted the inactivation, while the shading effect of particles reduced the inactivation at higher pH. The inactivation efficiency was enhanced by the presence of SRNOM and the photosensitizing effect of kaolinite particles.

Summary: Compared with traditional liquid-liquid extraction, solid-phase extraction agents are important for the recovery of indium metal due to their convenience, solvent-free nature, and high activity. In this study, P2O4 was chemically modified using UiO-66 to form a solid-phase extraction agent, P2O4-UiO-66-MOFs, which showed excellent adsorption capacity for In(III). The adsorption process followed pseudo first-order kinetics and the adsorption isotherms fitted the Langmuir model. The modified P2O4-UiO-66-MOFs showed high stability and retained over 99% of the adsorption capacity after multiple cycles of adsorption-desorption-regeneration.

Summary: The interaction between groundwater matrices and nanoscale zero-valent iron (NZVI) affects the mobility of NZVI. In this study, polyacrylic acid-stabilized NZVI and Mg(OH)2-coated NZVI were investigated as representative stabilizers for NZVI. The presence of divalent cations and humic acid induced aggregation and sedimentation of NZVI-PAA, while encountered groundwater electrolytes could not effectively provide electrostatic repulsion. However, sonication of the NZVI slurry with groundwater eliminated the sedimentation behavior. In comparison, the settling behavior of NZVI@Mg(OH)2 was hindered, and it exhibited higher mobility after adsorption sites of the sand surface were exhausted.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
