Abstract

The present invention belongs to the field of determination of the dissolved gas content and the isotope composition in water, and specifically discloses an extraction and purification system and an extraction and purification method for dissolved xenon in water. The extraction and purification system comprises a water sample release and dissolved gas extraction system, and a gas purification and separation system communicated to the water sample release and dissolved gas extraction system. The extraction and purification method comprises: 1, carrying out baking and vacuum degassing on the whole system; 2, releasing a water sample, and extracting gas; 3, transferring the gas into a glass cold trap; 4, transferring the gas to a purification system; 5, further drying the precipitated gas; 6, adsorbing and removing the active gas; and 7, separating xenon. With the system and the method of the present invention, the problems of incomplete steam removing and incomplete xenon separation during the xenon extraction and separation process are solved.

Description

technical field [0001] The invention belongs to the field of determination of dissolved gas content and isotope composition in water, and in particular relates to an extraction and purification system for dissolving xenon in water and an extraction and purification method thereof. Background technique [0002] The determination of dissolved xenon and isotopic composition in water plays a very important role in tracer in the leakage monitoring of nuclear military industry and civil nuclear power plants. Under the condition of avoiding air pollution, reasonable sampling and complete extraction of dissolved xenon are the key to complete the content and isotopic composition of xenon in water. premise. [0003] In terms of sampling, glass tubes are basically used in China and glass valves are used to seal the samples at both ends. This method has two disadvantages: 1) The valve has a dead angle, and it is difficult to completely drive away the air bubbles 2) The glass container m...
