Abstract

The invention discloses a hydrogen and oxygen isotope fractionation experimental device for teaching, and a use method, belonging to the technical field of fractionation experimental devices, and aiming at solving the technical problem that the hydrogen and oxygen isotope fractionation experimental device in the prior art cannot simulate the process of earth water cycle. An evaporation unit is used for heating a sample, so that the sample is evaporated into a gaseous state. The gaseous sample is condensed into liquid in a condensing unit, and the liquid is conveyed to a landing unit through aconveying pipe. The landing unit is used for simulating various landing environments of the liquid sample. The evaporation unit, the condensing unit and the landing unit constitute the process of earth water cycle. A sampling unit is used for taking samples at different stages in the process of the earth water cycle. The hydrogen and oxygen isotope fractionation experimental device simulates the entire process of the earth water cycle by setting the evaporation unit, the condensing unit, the landing unit and the like, and the sampling unit is used for taking samples at different stages in theprocess of the earth water cycle, so that relatively accurate experimental data is obtained, and the entire process of the earth water cycle and the temporal and spatial variation of hydrogen and oxygen isotopes in the process of the earth water cycle can be visually shown.

Description

technical field [0001] The invention belongs to the technical field of fractionation experiment devices, and in particular relates to a hydrogen and oxygen isotope fractionation experiment device for teaching and a usage method. Background technique [0002] Isotope fractionation refers to the phenomenon that different isotopes of an element are distributed between two or more substances (phases) with different isotope ratios during physical, chemical and biochemical processes due to the different isotopic masses. . Atmospheric water or rainwater refers to the general term for water such as rain, snow, rivers, lakes, groundwater, etc. that have recently participated in the atmospheric cycle. Water is composed of hydrogen and oxygen elements. There are three isotopes of hydrogen in nature: H (protium), D (deuterium) and a very small amount of T (tritium). The relative mass difference of hydrogen isotopes is the largest, and the isotope fractionation is also the most obvious....
