Problems solved by technology
[0002] Transferring the concentrated pool water to complete the secondary distillation is not only cumbersome, but also easily absorbs environmental moisture and causes pollution
[0003] Also, due to the residual loss in the pool water transfer process, the quality of the electrolysis-terminated water sample must be increased, resulting in a concentration ratio of m I / m F Reduced, which adversely affects the improvement of analytical uncertainty and detection limit

The invention belongs to the technical field of distillation equipment, and particularly relates to a secondary distillation system and a using method thereof. The secondary distillation system comprises a constant-temperature heating box, an electrolytic tank, a first stainless steel connector, a capillary exhaust pipe, a second stainless steel connector, a collecting bottle, a vacuum valve, a cold trap and a vacuum pump. The electrolytic tank is arranged in the constant-temperature heating box; the top outlet of the electrolytic tank is hermetically connected with the capillary exhaust pipe through the first stainless steel connector; the outlet end of the capillary exhaust pipe is connected with the collecting bottle through the second stainless steel connector; and the capillary exhaust pipe is further connected with a branch pipe, the vacuum valve is arranged between the capillary exhaust pipe and the branch pipe, the branch pipe is hermetically connected with the cold trap, and the vacuum pump is hermetically connected with the cold trap. In-situ vacuum low-temperature distillation can be simultaneously completed by the 24 electrolytic tanks, pool water is completely transferred into a receiving bottle under the condition that the pool water is not transferred, the conductivity of an obtained distilled water sample is very low, and a scintillation liquid can be directly added to prepare a test sample.
Description
technical field [0001] The invention belongs to the technical field of distillation equipment, and in particular relates to a secondary distillation system and an application method thereof. Background technique [0002] Transferring the concentrated pool water to complete the secondary distillation is not only cumbersome, but also easily absorbs environmental moisture and causes pollution. [0003] Also, due to the residual loss in the pool water transfer process, the quality of the electrolysis-terminated water sample must be increased, resulting in a concentration ratio of m I / m F This will adversely affect the improvement of analytical uncertainty and detection limit. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a secondary distillation system, which can completely transfer the pool water to the receiving bottle within 1 hour without transferring the pool water. [0005] In order to solve the above p...
