Abstract

The invention discloses a hydrogen and oxygen isotope fractionation experimental device for teaching and a method of use in the technical field of fractionation experimental devices, aiming to solve the technical problem that the hydrogen and oxygen isotope fractionation experimental device in the prior art cannot simulate the earth's water circulation process. The unit heats the sample to evaporate into a gaseous state, and the gaseous sample condenses into a liquid state in the condensation unit and is transported to the falling unit through the delivery pipe. The falling unit simulates various falling environments of the liquid sample; the evaporation unit, the condensation unit and the falling unit constitute the earth In the process of water cycle, the sampling unit samples at different stages in the process of the earth's water cycle. The present invention simulates the entire process of the earth's water cycle by setting up evaporation units, condensation units, and descending units, and samples each stage of the earth's water cycle through the sampling unit. , to obtain more accurate experimental data, and can visually display the entire process of the earth's water cycle and the temporal and spatial changes of hydrogen and oxygen isotopes in the process of the earth's water cycle.

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....
