Zusammenfassung:	PURPOSE: An adsorbing agent, a manufacturing method thereof, and a strontium/yttrium generator using the same are provided to extract 90[0020] Y of high purity while preventing extraction of toxic materials. CONSTITUTION: A method for separating 90Y from 90Sr/90Y liquid includes the following steps: adsorbing 90Y on an adsorption column in which an adsorbing agent is filled by passing the 90Y through the 90Sr/90Y liquid; washing the adsorption column with 0.1~0.5N nitric acid liquid to remove the 90Sr/90Y liquid and 90Sr; and extracting the 90Y with 3N nitric acid liquid. The 90Y liquid is separated in the adsorption column.
