Description
Shasha Yang and co-authors engineer in 2026 a sturdier way to zap a stubborn groundwater pollutant, 1,4-dioxane, out of drinking water at the point of use. Electric oxidation can destroy the suspected carcinogen, but single reactors demand heavy energy, scale up with minerals, wear out anodes, and breed perchlorate byproducts. Their design stacks several flow-through cells and pulses the current on and off in fifteen-second beats.
In synthetic groundwater, pulsing cut perchlorate formation sharply and suppressed scale. A four-stage pulsed unit ran for twenty days at a realistic trace concentration, removing roughly seventy percent of the pollutant per pass on average, with little voltage creep. Pairing stages with pulsing, the authors argue, fixes the failure modes that kept electric oxidation impractical for home-scale treatment.
