摘要

通过化学方法检测了水中脉冲放电产生的H2O2

通过拍摄照片研究流注长度的变化。实验发现

在分别通入氮气和氧气的情况下

随着气体流量和放电时间的增加

H2O2的浓度逐渐增加;在电极间距为5cm

所加电压为35kV时

通氮气比通氧气生成的H2O2多

通氮气时流注长度较通氧气时要长。在电极间距为3cm

所加电压为21kV时

通氧气比通氮气生成的H2O2多

而流注长度差异不大。

Abstract

Hydrogen peroxide is measured by chemical method in pulsed discharge in distilled water. Variation of the length of streamer is researched by taking photos. It is found that with increasing of gas-flow rate and discharge time

quantity of hydrogen peroxide increases gradually when nitrogen and oxygen is inlet respectively. When the distance of electrode is 5 cm and the applied voltage is 35 kV

the quantity of hydrogen peroxide formed in nitrogen-water mixture discharge is more than that in oxygen-water mixture discharge

and the streamer in nitrogen-water mixture discharge was longer than that in oxygen-water mixture discharge. However

when the distance of electrode is 3 cm

applied voltage is 21 kV

that formed in oxygen-water mixture discharge is more than in nitrogen-water mixture discharge

and the length of the streamer varies little.
