Interactions between pH, reactive species, and cells in plasma-activated water can remove algae.

ABSTRACT: Lightning strikes cause nitrogen to dissolve in water and form reactive nitrogen and oxygen species, which form natural fertilizers that can be absorbed through plant roots. Such processes during rainstorm events can be simulated by applying plasma to a solution. Plasma-activated water (PAW) has great potential as a source of various dissolved reactive chemical species. Different mixtures of species are produced using different solution compositions. Here, basil seeds were grown in PAW to prevent blooms of Chlorella vulgaris and ion chromatography and UV-vis spectroscopy were used to quantify reactive ions. NO₂ ^-, NO₃ ^-, and H₂O₂ were found to be key to the antialgal effect. Secondary reactive ions such as peroxynitri
