研究了低温等离子体和过氧化氢气溶胶组合对圆柱形容器桶内表面微生物净化的灭活效果，包括对一种细菌和七种丝状小霉菌以及空气污染的杯子的灭活效果。虽然单一的非热等离子体或过氧化氢的去污在120 s后不可观察到，但它们的组合在暴露30 s后发生强烈去污。此外，所观察到的塑料杯的空气传播污染的完全消除预先确定了该方法作为基于应用过氧化氢的当前使用的方法的合适替代方法。
The inactivation effect of the combination of nonthermal plasma and hydrogen peroxide aerosol for the microbial decontamination of inner surface of cylindrical container buckets is studied on one bacterial and seven filamentous micromycete species and on airborne-contaminated cups. While the decontamination by single nonthermal plasma or hydrogen peroxide is not observable after 120 s, the strong decontamination by their combination occurs after 30 s of exposure. Moreover, observed total elimination of airborne contamination of plastic cups predetermines this method as a suitable alternative to the currently used method based on the application of hydrogen peroxide.
