Abstract
A method and apparatus is provided for efficiently supplying a liquid with ions or radicals generated by plasma and so on, or for effectively sterilizing microorganisms present in a liquid or on the surface thereof. The method includes generating plasma in a gas phase by a plasma generation device, producing ions or radicals in the gas phase by the plasma; electrophoresing the ions or radicals toward the liquid by an electric field applied to the produced ions or radicals; and diffusing the ions or radicals into the liquid. The liquid is adjusted to have a pH value of 4.8 or lower for effective sterilization.
