Buffer and Salt Effects in Aqueous Host-Guest Systems: Screening, Competitive Binding, or Both?

Jacobs H. Jordan et al.

Summary: There are still many unresolved questions regarding the supramolecular properties of ions in water, and the mathematical models used by supramolecular chemists do not adequately account for screening effects. The study shows that both screening and competitive binding have significant impacts on affinity in buffered solutions, especially when the ionic strength changes significantly. The competitive mathematical model proposed in the study suggests that competitive binding to the host is a major factor for binding attenuation in buffer systems, outweighing the effect of screening.

Efficient Removal of Per- and Polyfluoroalkyl Substances from Water with Zirconium-Based Metal-Organic Frameworks

Rui Li et al.

Summary: The study demonstrates that the zirconium-based metal-organic framework NU-1000 shows exceptional adsorption capacities and ultrafast adsorption kinetics for PFASs, with equilibrium times of less than 1 minute. NU-1000 also exhibits excellent regeneration and reusability characteristics, with nearly quantitative removal and recovery rates after five consecutive adsorption and desorption cycles of PFAS. Adsorption testing using PFAS-contaminated groundwater samples shows impressive PFAS removal rates of 75-98% within 10 minutes, regardless of the presence of co-contaminants.

Bioactivity profiling of per- and polyfluoroalkyl substances (PFAS) identifies potential toxicity pathways related to molecular structure

Keith A. Houck et al.

Summary: Per- and polyfluoroalkyl substances (PFAS) are a group of chemicals of environmental concern due to their widespread presence and persistence. In this study, 142 PFAS were evaluated and some were found to be associated with various nuclear receptor activities, which can guide future predictive modeling for prioritizing chemicals for risk assessment.
