Description
Technical Field
The invention belongs to the technical field of cores, and particularly relates to a method for screening isotope-containing liquid separation membranes in a large scale.
Background
Treatment of liquids containing different isotopic elements involves multiple fields, such as treatment of tritium (T) containing liquids in the nuclear energy field (X.X.Mei, L.P.Xiong et al Analytical Chemistry,2010,33,201-206), and H for PET in the medical industry 2 18 O preparation (J.K.Choi, D.S.Chang et al, ind. Eng. Chem. Res.2009,48, 5431-5438).
According to the related literature (Ming Wen et al Journal of Membrane Science,2020, 610,118237), a novel graphene hydrophobic membrane can be prepared by a simple process, and H can be realized by combining the characteristics of membrane distillation 2 O/D 2 O (or H) 2 O/HDO) and the like, and similarly H 2 16 O/H 2 18 O can also be separated by membrane distillation according to literature (Rasoul Moradi et al, chemical Engineering and Processing,2016,100,26-36). In order to prepare a high-performance separation membrane, an experiment of membrane distillation needs to be carried out, and separation performance of each membrane sample prepared in the experiment is tested. The relevant literature (GJ Sevigny et al, separation of tritiated water using graphene oxide membrane, 2015) shows that the use of heavy water (D) 2 O, HDO) and tritium water (T) 2 O, HTO) do separately to H 2 O separation, the separation results have a certain similarity, so that H is commonly used in research on low tritium liquid treatment in view of safety, simplification and the like due to tritium radioactivity 2 O/D 2 O (or H) 2 O/HDO) is used as a research object, and the related result can be H 2 O/T 2 O (or H) 2 O/HTO) provides guidance.
In the prior art, the performance test of the separation membrane in the related literature (GJ Sevigny et al Separation of tritiated water using graphene oxide membrane, 2015) adopts the following two methods:
(1) Under the condition of controlling air flow, the transmission performance of the graphene film is preliminarily tested by measuring the weight loss of water vapor transmitted through the graphene oxide film within a certain time. Although the method can test a plurality of membrane materials simultaneously and provide certain performance test data, the method takes a long time (more than 1000 hours);
(2) Another method is a method of passing water vapor through experiment after vaporization at high temperature, which requires special equipment and unstable membrane material, and each experimental facility of the current test method can test only one membrane.
For performance testing of separation membranes for membrane distillation applications, the current testing method only can test one membrane per experimental facility, and if multiple membranes need to be tested simultaneously, multiple sets of membrane distillation testing equipment are needed, so that the overall cost of testing is high.
Therefore, the method for large-scale screening of the isotope liquid separation membrane can be used for testing the separation performance of a plurality of membranes at one time, so that the process of screening the membrane is short in testing time, high in efficiency and low in testing cost, and the method becomes a problem to be solved by the technicians in the field.
