This project seeks to develop plasma gas-liquid reactors to produce chemical disinfectants (e.g., hydrogen peroxide and hydroxyl radicals) through plasma formation. Previous support from NSF has provided knowledge of the basic chemical reactions and the mechanisms for the formation of reactive species including hydroxyl radicals and hydrogen peroxide in small laboratory scale reactors where non-thermal plasma contacts with liquid water. The research team has discovered that higher efficiencies can be obtained when plasma formed in the gas phase contacts a flowing liquid film or an aerosol of water droplets and used this to develop a reactor system. The reactor system developed is quite simple, durable, and robust. While it is currently of relatively small laboratory scale, we expect that the scale up can be addressed so that the system can have a potential impact on the market for small processing plants and perhaps personal use where portability and low unit expense are needed.The development of new technologies for disinfection, water cleaning, and chemical oxidation can address many public health and environmental problems as well as improve industrial efficiency.Small scale efficient gas-liquid plasma reactors may find wide use in a variety of such applications.

该项目旨在开发等离子体气液反应器，通过等离子体形成来生产化学消毒剂(如过氧化氢和羟基自由基)。NSF以前的支持提供了关于基本化学反应的知识，以及在小型实验室反应器中形成活性物种的机制，包括羟基自由基和过氧化氢，在那里，非热等离子体与液态水接触。研究小组发现，当气相中形成的等离子体与流动的液膜或水滴的气溶胶接触并利用这一点开发反应堆系统时，可以获得更高的效率。开发的反应堆系统非常简单、耐用和坚固。虽然目前它的实验室规模相对较小，但我们预计可以解决规模扩大的问题，以便该系统能够对小型加工厂的市场产生潜在影响，并可能在需要便携性和低单位成本的个人使用市场上产生影响。开发消毒、水清洁和化学氧化的新技术可以解决许多公共健康和环境问题，并提高工业效率。小型高效气液等离子反应器可能会在各种此类应用中得到广泛应用。
