Electrolytic tank adopting stainless steel capillary tube for exhausting

Abstract

The invention discloses an electrolytic tank adopting a stainless steel capillary tube for exhausting, and relates to the technical field of electrolysis. The electrolytic tank comprises an outer electrode used for containing electrolyte and an inner electrode arranged in the outer electrode, a first flange is arranged at a port of the outer electrode, the inner electrode is tubular, a stainless steel capillary tube used for exhausting is arranged at a top port of the inner electrode, a second flange matched with the first flange is arranged on the outer side of the inner electrode, and the first flange and the second flange are installed in an insulating mode. According to the invention, concentration factor reduction and analysis uncertainty increase caused by spray loss are avoided, and water sample pollution caused by absorption of environmental water vapor is avoided.

Description

technical field [0001] The invention relates to the technical field of electrolysis, in particular to an electrolytic cell using stainless steel capillary exhaust. Background technique [0002] In the electrolytic concentration process of the preparation of tritium analysis samples, an electrolytic cell is required. When using it, the electrolytic cell needs to be installed. After being placed in a constant temperature bath, the electrolysis must be performed after the temperature is balanced. After the electrolysis is automatically completed, the electrolytic cell is often still It should be placed in the constant temperature tank for a certain period of time, during which the inner wall of the electrolytic cell and the pool water at low temperature are likely to absorb environmental moisture and cause pollution. As a result, certain system errors are introduced and the detection limit is increased. [0003] O produced during electrolysis 2 and H 2 Continuously overflowin...

[0002] In the electrolytic concentration process of the preparation of tritium analysis samples, an electrolytic cell is required. When using it, the electrolytic cell needs to be installed. After being placed in a constant temperature bath, the electrolysis must be performed after the temperature is balanced. After the electrolysis is automatically completed, the electrolytic cell is often still It should be placed in the constant temperature tank for a certain period of time. During this period, the inner wall of the electrolytic cell and the pool water at low temperature are likely to absorb environmental moisture and cause pollution. As a result, a certain system error is introduced and the detection limit is increased.

[0003] O produced during electrolysis 2 and H 2 Continuously overflowing the water surface to form a spray, O 2 and H 2 , will bring water vapor out of the cell, which will lead to a decrease in the concentration factor and an increase in the uncertainty of the analysis
