Abstract
Efficiently produce micro-dispersion water of super-fine noble metal particles having a desired concentration by using a very safe, compact production apparatus comprising a power supply for high-voltage/current discharge, a high-voltage discharge generator equipped with a noble metal electrode and its counter electrode, a water tank, a water inlet to the water tank, and an outlet for micro-dispersion water of super-fine noble metal particles, by causing plasma discharge in water between the noble metal electrode and its counter electrode and then causing the generated noble metal ion vapor to contact, and micro-disperse in, water. The obtained water can be effectively used as drinking water.
