Summary:PURPOSE: A preparation process of tourmaline solution through simple chemical reaction on a large scale is provided. CONSTITUTION: The preparation process of tourmaline solution includes the steps of adding alkali to water to be treated with tourmaline; adding tourmaline powder to the alkali solution in a weight ratio of 1 : 10 to 40; pouring 5 to 10 vol.% of iron chloride(25%) to 100 vol.% of resultant solution of a second step; adjusting hydrogen-ion concentration to be pH 8 to 9; and settling resultant solution of a third step to obtain a tourmaline solution.
