PURIFIER AND PURIFICATION METHOD

To provide a purification method and a purifier capable of suppressing pressure rise in a flow line of a solution, when dissolving a target by an acidic solution, for improving purity in purification of nuclide.SOLUTION: There is provided a purifier for purifying nuclide from a target on which the nuclide is generated on a surface thereof, the purifier comprising: a dissolution part for bringing the surface of the target into contact with an acidic solution for causing a dissolution solution including the nuclide to flow out; and a gas discharge part for discharging to outside of the dissolution part, a gas generated by contact of the target and the acidic solution. The purifier comprises: an acidic solution supply part for supplying the acidic solution to the dissolution part; and a dissolution solution reception part to which the dissolution solution is supplied from the dissolution part, and the gas discharge part is provided on the dissolution solution reception part.SELECTED DRAWING: Figure 6 【課題】ターゲットを酸性溶液によって溶解させる際に、溶液の流動経路内の圧力の上昇を抑制して、核種の精製における純度を向上すること。【解決手段】表面に核種が生成されたターゲットから、核種を精製する精製装置であって、ターゲットの表面を酸性溶液に接触させて、核種を含む溶解溶液を流出させる溶解部と、ターゲットと酸性溶液との接触によって生じた気体を溶解部の外部に排出する気体排出部と、を備える。溶解部に酸性溶液を供給する酸性溶液供給部と、溶解部から溶解溶液が供給される溶解溶液受給部と、を備え、気体排出部が溶解溶液受給部に設けられている。【選択図】図６
