This application discloses a separation device for radioactive waste liquid. Each separation component has a connected separation chamber and a storage chamber. The separation chamber is used to contain separation resin, and the storage chamber is used to store eluent. A connecting member is correspondingly disposed on the separation component and located on one side of the storage chamber. The connecting member has a through-hole pressurization port. The pressurization component is detachably connected to the connecting member, and the pressurization component can deliver a pressure medium to the storage chamber through the pressurization port. In this application, the pressurization component in the separation device can output a pressure medium, which is transmitted to the storage chamber through the pressurization port to pressurize the eluent, effectively solving problems such as slowed rinsing and stagnation of rinsing, quickly obtaining the analytical solution to be analyzed after removing the radioactive matrix, and improving the analytical detection efficiency. At the same time, it avoids interference with operation by stirring, eliminates the possibility of introducing other contaminants due to stirring, and ensures the accuracy of detection of the analytical solution.
