The influence of low-temperature plasma on the electromagnetic spectrum structure of the selected liquid

The aim of the research was to parameterise the degree of influence of low-temperature plasma on the structure of the electromagnetic spectrum in the visible light range of a selected fluid, which, after being parameterised, will constitute a benchmark marker of the analysed interaction. The scope of the research included the generation of plasma water in a plasma generator, the intensity of which was the differentiating element. The fluid so prepared was subjected to spectral analysis. Subsequently, water of varying interaction degree was used to prepare a medium for microorganisms, the growth of which was monitored by measuring the optical density of the solution. Differences were also observed in the kinetics of microbial growth, which developed in water subjected to cold plasma interaction and in water without this interaction. The measured optical density after a 6-fold exposure and 50-hour incubation was 3.72 McF and was 1.93 McF lower than that of the reference sample (without exposure).
