PFAS chemicals do not last forever

The use of sulfite and iodide under ultraviolet light can destroy PFAS in water in a few hours

25-May-2022

Once dubbed “forever chemicals,” per-and polyfluoroalkyl substances, or PFAS, might be in the market for a new nickname. That’s because adding iodide to a water treatment reactor that uses ultraviolet (UV) light and sulfite destroys up to 90% of carbon-fluorine atoms in PFAS forever chemicals in ...

Making light work of emerging micropollutants

Dangerous and environmentally harmful organic micropollutants can be successfully removed from wastewater using high-intensity pulses of light

12-Jan-2022

Carbon-based organic micropollutants in water can be removed by treatment with high-intensity pulses of light in a procedure developed and demonstrated by researchers at KAUST. This photodegradation process was already known to be feasible, but its use was limited by the long treatment times it ...
