Problems solved by technology

Carbonyl sulfide is also more harmful to the environment and can cause water pollution
[0004] The detection of carbon oxysulfide can mainly take advantage of its characteristics that it is easy to react with oxidants, and measure the content of sulfur element in it to determine its content. However, it has the characteristics of complicated operation, long feedback time, and is easy to be interfered. Therefore, Cause some inconvenience to the rapid detection of carbonyl sulfide

Abstract

The invention discloses a carbon oxysulfide detection reagent and a preparation method thereof and belongs to the technical field of gas detection. The carbon oxysulfide detection reagent is composed of, by mass, 5-10 parts of zinc nitrate, 2-6 parts of zinc oxide, 3-8 parts of sodium borate, 12-22 parts of potassium hypermanganate, 1-4 parts of calcium alkyl salicylate, 2-5 parts of triphenylmethanol and 12-20 parts of deionized water. The preparation method includes the following steps: (1), preparing a premixed solution; (2), obtaining a clear mixed solution; (3), sealing after vacuum standing for 4-8h to obtain the carbon oxysulfide detection reagent. A carbon oxysulfide colorimetric method has the advantages of sensitivity in reaction, high detection accuracy and easiness in operation, and low-concentration carbon oxysulfide in environment can be detected quickly and quite conveniently.

Description

technical field [0001] The invention belongs to the technical field of gas detection, in particular to a carbon oxysulfide detection reagent and a preparation method thereof. Background technique [0002] Carbonyl sulfide, also known as carbon sulfide and carbonyl sulfide, is usually a colorless gas with the smell of rotten eggs. It is an inorganic carbon compound structurally similar to carbon disulfide and carbon dioxide. Carbonyl sulfide is stable, but reacts strongly with oxidizing agents and corrodes metals in the presence of moisture. Carbonyl oxysulfide is flammable and toxic. Like hydrogen sulfide, people will underestimate its concentration in the air. [0003] The harmfulness of carbonyl oxysulfide to the human body is similar to that of hydrogen sulfide, and it is slightly irritating to the lungs. When the concentration is high, the human body may convulse, which is more harmful to the human body. Carbonyl oxysulfide is also more harmful to the environment and ...
