Nanofiltration for cleaner water is stopping one of farming's most persistent chemicals from slipping through

Phys · · 681 words · By Sandra Wiebe

The article discusses research findings from the Karlsruhe Institute of Technology regarding the use of nanofiltration membranes to remove herbicides, specifically glyphosate and its metabolite AMPA, from water. Researchers determined that the removal efficiency is influenced not only by molecular size and charge but also by the hydration shell surrounding the molecules and the solution's pH level. These findings aim to improve water purification technologies globally.
