The chemical characteristics of atmospheric pressure dielectric barrier discharge plasma generated in air are very sensitive to some factors, such as environment temperature and discharge power. There are two typical modes, namely the ozone mode and nitrogen oxides mode. In this paper, the air surface micro-discharge plasma in the ozone mode and nitrogen oxides mode are respectively generated at environment temperatures of 5 °C and 50 °C when discharge power is almost kept at 6 W, and the plasma-activated water (PAW) is prepared by means of passing the plasma exhaust gases into deionized water. By comparing the reactive species in PAW under these two modes and their sterilization effects, it is found that the concentrations of H + , H 2 O 2 , NO 2 − , NO 3 − and ONOO − in PAW for the nitrogen oxides mode are about 2–3 fold over those for the ozone mode, while the concentration of O 3 in PAW f...

空气表面微排放物的模式转变及其对水活化和抗菌活性的影响

空气中产生的大气压介质阻挡放电等离子体的化学特性对某些因素（例如环境温度和放电功率）非常敏感。有两种典型模式，即臭氧模式和氮氧化物模式。在本文中，当放电功率几乎保持在6 W时，在5°C和50°C的环境温度下分别产生了臭氧模式和氮氧化物模式的空气表面微放电等离子体，而等离子体活化水（通过使等离子废气进入去离子水中来制备。通过比较两种模式下PAW中的反应性种类及其杀菌效果，发现H +，H 2 O 2，NO 2-，
