Abstract

A disclosed measuring method for inorganic anions of glacier water is characterized by utilizing a plasma chromatography method and combining a self-made ion exchange chromatographic column to analysis a snow-ice sample solution, so that the chromatographic peak resolution of high-concentration chloride ion and low-concentration nitrites is substantially improved. Compared with the prior art, the measuring method is low in equipment price, short in measuring time, less in usage amount of consumed materials, low in detection cost and high in measuring precision.

Description

Technical field

[0001] The invention relates to the measurement of inorganic anions, in particular to a method for measuring inorganic anions of glacier water. Background technique

[0002] Snow ice is a storage reservoir of various substances in the atmosphere, an indicator of climate and environmental changes, and an important source of information on global climate and environmental changes. Snow and ice chemistry has become an important content of global change research. The anions and cations in snow and ice are reliable indicators that reflect climate change and environmental evolution. Therefore, studying the sources and transmission mechanisms of anions and cations and their secondary changes in snow and ice can not only restore the evolution of climate and environment. , And more importantly, it can provide new evidence of interactions between geospheres, especially for the study of the migration and transformation of substances between the atmosphere, lithosphere, hydro...
