KI-starch solution during plasma jet treatment

These videos show bottom and side views of the treatment by a He/O2 plasma jet of a solution containing ultra-pure water, potassium iodide and starch. As the plasma reaches the liquid, a purple filament characteristic of the triiodide ion/starch complex appears. This complex is formed by the reaction between iodide ion and a reactive oxygen and nitrogen species (RONS) such as ozone, hydrogen peroxide, hydroxide ion, nitric oxyde or nitrate. Therefore, the formation of these RONS in the liquid phase is temporally and spatially quantified.

本数据集展示了对含有超纯水、碘化钾和淀粉的溶液进行He/O2等离子体喷射处理的底部和侧面视图。当等离子体接触到液体时，出现了一种由三碘化物离子/淀粉复合物特有的紫色细丝。该复合物由碘离子与活性氧和氮物种（RONS）如臭氧、过氧化氢、氢氧根离子、一氧化氮或硝酸盐之间的反应形成。因此，这些RONS在液体相中的生成在时间和空间上得到了量化和分析。
