An herbal infusion and a clay for chromium removal from water
In this work, a response surface methodology (RSM) was used to attain optimal conditions for polyphenols extraction from Yerba Mate (YM, South-America infusion) using water as solvent under ultrasound. The following parameters were varied: mass of YM/volume of water (YM/W), pH, temperature, and time. This study helps to developing an eco-friendly and cost-effective experimental design, reducing the production of wastes, and using a very fast water-based method for the extraction.

EPA Report on PFAS Strategic Roadmap: Three Years of Progress
The Environmental Protection Agency (EPA) has released a comprehensive report detailing three years of progress on its PFAS Strategic Roadmap, originally introduced in 2021 to tackle per- and polyfluoroalkyl substances (PFAS) contamination across air, land, and water. The Roadmap is built on three core objectives:
Emerging Solutions at the Critical Intersection of Plastics, Water, and Green Chemistry

Models to Predict the Removal of Emerging Micropollutants from Water by Novel Adsorbents in Fixed-Bed Column Processes
The U.S. Environmental Protection Agency (EPA), through the Innovative Water Technology Grant Program, is seeking applications for research to develop, test and deploy predictive models for novel adsorbents and estimate the effectiveness of these adsorbents to remove emerging micropollutants in drinking water and wastewater treatment operations.
