| titleOfInvention | Method for regenerating basic ion exchange resin, method for measuring chlorine ion concentration using regenerated ion exchange resin, and measuring apparatus therefor |
| abstract | (57) 【Abstract】 PROBLEM TO BE SOLVED: To regenerate a basic ion exchange resin suitable for measuring chlorine ion concentration. A glass column 10 is filled with a basic ion exchange resin 14. After passing ultrapure water in the container 30 to wash it, an alkaline aqueous solution in the container 31 is passed to perform an alkali treatment for substituting the base in the ion exchange resin with a hydroxyl group. Then, after passing ultrapure water to wash with water, the container 32 Carbon dioxide is driven out by passing a neutral salt solution inside. After that, after passing ultrapure water to wash with water, an acidic solution in the container 33 is passed to perform an acid treatment for expelling alkali ions, Pass ultrapure water and wash with water. Next, the alkali treatment and the acid treatment are performed again, and then the product is washed with water. |
