This research combines foam fractionation and ultraviolet treatment to permanently remove PFAS "forever chemicals" from contaminated water. By first concentrating PFAS into foam and then destroying their strong carbon–fluorine bonds with UV-generated reactive species, the approach offers a more efficient and sustainable alternative to conventional treatment technologies.

This research improves iron oxide nanoparticles for pollutant removal by addressing aggregation issues. Using pectin surface modification, particularly low methoxyl pectin via functionalization, enhances stability and adsorption efficiency. The modified nanoparticles achieve up to 95% methylene blue removal, demonstrating a significant improvement for environmental remediation applications.
