The present invention relates to a new ion exchange method. Currently, commercially available anion exchangers are copolymers of divinylbenzene and styrene with alkylamino groups such as dimethylamino groups, trimethylammonium groups, alkylammonium groups, or functional groups such as hydroxymethylamino groups. However, these do not necessarily have excellent durability and chemical resistance. As a result of repeated studies from this standpoint, the present inventors discovered an ion exchanger made of a three-dimensionally crosslinked copolymer having a novel chemical structure, leading to the present invention. That is, the present invention relates to a method of using a substance having a novel chemical structure as an ion exchanger. The ion exchanger used in the present invention is a three-dimensional crosslinked copolymer containing 20 to 98 mol% of polymerized units represented by the following structural formula (). Here, R represents hydrogen or a hydrocarbon group having 1 to 4 carbon atoms. Also, Z represents the following (a) or (b).

[Table] Example 1 10 ml of ion exchangers No. 1 to No. 5 (free type) were packed into a glass cylindrical column equipped with a filter and a pot with an inner diameter of 10 mm, and 0.5N sodium hydroxide solution and distilled water were added. 200 ml was poured in sequence. At this time, the pH of the liquid that finally flowed out was 7.
Next, the cap at the bottom of the column was closed, 2 ml of 0.5N hydrochloric acid was added to the column, and distilled water was subsequently added so that the liquid level was the same as the height of the top of the ion exchanger. After leaving the column in this state for one day and night, the column was opened and the liquid inside the column was collected. This liquid is No.1~
No chlorine ion was detected in any of No. 5. Next, pour a 1N potassium nitrate solution into each of Nos. 1 to 5 until no chlorine ions are detected in the solution flowing out from the bottom, and then remove the chlorine ions in these solutions with a silver nitrate solution. As a result of titration, 1 mmol of chlorine ion was detected in each case.
