Abstract

The concentration of hydrogen peroxide and hydroxyl radicals in dependence of the intensity (strength) of water drop impact on a solid surface has been measured. The intensity was varied by changing the fall height from 1 to 4 m and the tilt angle of the surface onto which drops fell. It is shown that the content of hydrogen peroxide and hydroxyl radicals in solution increases after the drop impact on the solid surface. Apparently, the main mechanism of the observed effects is the generation of singlet oxygen and its further reduction.

水滴落在固体表面过程中活性氧的生成

摘要测量了过氧化氢和羟基自由基的浓度与水滴撞击固体表面的强度（力度）的关系。水滴落下的高度从 1 米到 4 米不等，水滴落下表面的倾斜角度也随之变化。结果表明，水滴撞击固体表面后，溶液中过氧化氢和羟基自由基的含量会增加。显然，观察到的效应的主要机制是单线态氧的产生及其进一步还原。
