Plasma Liquid Chemistry Of Pulse Discharges Generated In Water Depending On Pulse Duration And Ground Electrode Materials

Persistent organic pollutants such as pharmaceutical residues, often withstand treatment by conventional water treatment methods. However, plasmas generated directly in water have shown to effectively decompose these compounds and are a promising new approach. So far, research conducted on this topic, has primarily focused on the application of positive micro- to millisecond high voltage pulses and on associated degradation rates. Sub-microsecond pulses, possible effects due to electrode material and detailed degradation pathways, however, received little to no attention.
