Abstract- This paper deals with the challenging research topic of the use of low-temperature plasmas at atmospheric pressure for the treatment of pharmaceutical residues in water. The low-temperature plasmas were generated in a multiple needle-to-plate reactor. Using ICCD imaging and electrical measurement, two distinct discharge regimes were identified. Optical Emission Spectroscopy (OES) measurements evidenced the OH production and enabled determination of the rotational temperature. An analgesic (paracetamol) in aqueous solution was treated with this reactor, and its conversion rate was 81% after 60 min of treatment.
