- 摘要：
PROBLEM TO BE SOLVED: To provide a method for separating iodine simply in a short time without adding additives or chemical substances, because an oxidation-reduction potential is required to be low as much as possible, whereas, although a large quantity of iodine originated in seaweed is contained in aqueous solution extracted from ash obtained by incinerating plants containing seaweed, and plant incinerated product extract containing seaweed is sometimes utilized for the purpose of improving physical conditions because of having abundant minerals, there is a problem wherein the large quantity of contained iodine is required to be reduced for every day ingestion.
SOLUTION: In this method, iodine can be separated in several hours without raising the oxidation-reduction potential, while preventing decrease of minerals in the plant incinerated product extract. Iodine in the plant incinerated product extract solution can be reduced from 105 ppm to 5.5 ppm in 3-4 hours, by using jointly three methods, namely a method for stirring aqueous solution and a resin, a method for adding a large quantity of resin into the aqueous solution, and a method for adding resin dividedly into two stages.
