説明

This study examined the electrification quantity of the fog in doing ultrasonic atomization of pure water. In the water of low purity, the electrification fog in proportion to the induced voltage polarity arose. However, in the water of high purity, the electrification fog of the negative polarity arose with no relation to the application of negative induced voltage. Especially, it was found that the negative charged fog arose, even when the induced voltage was not applied in the high-pure water. From this fact, when the purity of the water rises, the electric double layer which exists in air/water interface, seems to have firmly been formed. This fact was supported from the measurement results in mixing the surfactant. In addition, the generation of the electrification fog was promoted, when the chemical compound with hydroxyl group dissolved.
