Problems solved by technology

[0004] Existing methods for measuring hydrogen fluoride are mainly colorimetric methods and electrochemical methods, among which colorimetric methods, the existing colorimetric methods mainly utilize fluorine reagents to form complexes with rare earth salts for colorimetric quantification, but due to interference factors More, the sensitivity of its determination is low, and the range of determination is narrow, and it can only be qualitatively determined in the environment with high content. Therefore, it is not conducive to accurate determination in the environment with low content.

Abstract

The invention discloses a hydrogen fluoride detection reagent and a preparing method thereof and belongs to the technical field of gas detection. The reagent comprises, by weight, 5 to 12 parts of lanthanum trichloride, 2 to 8 parts of antimony pentafluoride, 2 to 8 parts of potassium nitrate, 3 to 6 parts of triethanolamine oleate, 2 to 7 parts of n-butyl alcohol, 3 to 8 parts of sodium sulfate, 4 to 10 parts of aluminum chloride, and 12 to 18 parts of deionized water. The preparing method includes the steps of 1, preparing premixed liquid; 2, acquiring clarified mixed liquid; and 3, allowing vacuum standing for 12 to 48 hours and performing sealing to obtain the hydrogen fluoride detection reagent. The hydrogen fluoride detection reagent is of high response speed and high accuracy, the problem that the prior art is poor in precision is effectively solved, and the content of hydrogen fluoride can be detected effectively and quickly.

Description

technical field [0001] The invention belongs to the technical field of gas detection, in particular to a hydrogen fluoride detection reagent and a preparation method thereof. Background technique [0002] Hydrogen fluoride is a binary compound composed of fluorine and hydrogen. It is a colorless gas with a pungent odor. The aqueous solution of hydrogen fluoride is called hydrofluoric acid. Hydrogen fluoride is a raw material for various fluorine-containing compounds and has various properties. [0003] Both hydrogen fluoride and its aqueous solution are highly toxic and generally enter the human body through the respiratory tract, easily deforming bones and teeth. Hydrofluoric acid can be absorbed through the skin by mucous membranes, respiratory tract and gastrointestinal tract. [0004] Existing methods for the determination of hydrogen fluoride are mainly colorimetric methods and electrochemical methods, among which colorimetric methods, the existing colorimetric methods...
