PRLog -- Plasmas operating at atmospheric pressure in ambient air produce a wide range of reactive chemical species. When an atmospheric plasma is allowed to interact with water, a unique mixture of biochemically reactive chemistries occur, and the resultant chemically active water is referred to as Plasma Activated Water (PAW). Due to its unique biochemical activity, PAW is a promising technology in food, agricultural and biomedical industries and is a possible environmentally friendly alternative to chemical fertilisers. PAW has been shown to be effective at food decontamination, seed germination and improved plant growth [1-3].
In this short contribution, we report on PAW created using Henniker's 'Cirrus' atmospheric plasma system [4]. We present measured changes in pH, conductivity, and nitrate levels as a function of plasma-water interaction time and, in collaboration with Hiden Analytical, we report membrane inlet mass spectrometry (MIMS) measurements of dissolved species in PAW using the Hiden HPR-40 dissolved species analyser (HPR-40 DSA) [5]. The effectiveness of the PAW was tested by comparing the growth and longevity of cut roses in samples of PAW and untreated water.
