在装有电极的石英管中流动的水中的Ar气泡中产生了射频辉光等离子体。气泡中的等离子体（简称“气泡等离子体”）可用于诱导液体中的一些特定化学反应。研究表明，气泡等离子体可以分解溶解在水中的亚甲基蓝（MB），并且在气相等离子体中存在羟基（OH）自由基。因此，可以推测MB的分解是由气泡等离子体中产生并扩散到水溶液中的OH自由基直接引起的，或者是由溶液中形成的这种OH自由基的衍生物间接引起的。
Radio-frequency glow-like plasmas have been produced in Ar bubbles in water that flows in a quartz tube equipped with electrodes. Plasmas in bubbles, (or 'bubble plasmas' in short) may be used to induce some specific chemical reactions in liquids. It has been demonstrated that bubble plasmas can decompose methylene blue (MB) dissolved in water and hydroxyl (OH) radicals are present in the gas-phase plasmas. Therefore it may be presumed that decomposition of MB is caused either directly by OH radicals that are generated in the bubble plasmas and diffuse into the aqueous solution or indirectly by derivatives of such OH radicals formed in the solution.
