Confined Metastable 2‐Line Ferrihydrite for Affordable Point‐of‐Use Arsenic‐Free Drinking Water

Abstract

Arsenic-free drinking water, independent of electrical power and piped water supply, is possible only through advanced and affordable materials with large uptake capacities. Confined metastable 2-line ferrihydrite, stable at ambient temperature, shows continuous arsenic uptake in the presence of other complex species in natural drinking water and an affordable water-purification device is made using the same.
