PURPOSE:To simplify a device, by a method wherein a device consists of a sample water collecting means equipped with a quantative mechanism, a filtering tank for filtering the sample water, and an ion exchanging column connected directly to the filterint tank through a filter. CONSTITUTION:A sample water treating device consists of a collecting tank 16 combined with a quantative tank, and a direct-connection type ion exchanger in which a filter and an ion exchanger are united into a unity. To simultaneously execute a filteration and an ion exchange, a filtering tank 2 is connected directly to a column 12 through a rollform filter 3. Through the vertical movement of a sample water pan 13, the filtering tank 2 is connected to and is disconnected from the column 12, and the connection part keeps air tightness by means of a rolling seal and other materials. Thus, the filtering of the sample and the ion exchange can be simultaneously carried out through the suction of a vacuum exhaust pump 18. This simplifies a device, facilitates cleansing, and permits the prevention of the discharge of unnecessary radioactive liquid. |
