Název v původním jazyce

Plasma-assisted decomposition of atrazine traces in water

Popis výsledku v původním jazyce

Plasma discharge is a promising technique for micropollutant decomposition, since it produces a wide spectrum of highly reactive species near the water surface. In this research, two DBD reactors with a water electrode were investigated on energy yield of H2O2 production, ozone production and atrazine decomposition, in comparison to a reference reactor based on diaphragm discharge. Energy yield of atrazine decomposition is two orders of magnitude higher in the DBD reactors. They can be further optimizedby adding a membrane or active carbon textile with high surface area underneath the water surface. Adsorption of the micropollutant on such membrane or textile leads to higher decomposition rate at the plasma-liquid interface, without changing the inputpower. The synergetic combination of liquid plasma with nanofiber membrane or carbon cloth is a convenient water treatment technology, which can easily be scaled up to industrial level.
