Abstract

The invention discloses a carbon monoxide detection reagent and a preparation method thereof. The detection reagent consists of the following components in parts by weight: 0.5-1 part of ethylenediaminetetraacetic acid disodium salt, 1-2.5 parts of calcium chloride, 0.2-0.4 part of carzenide, 10-20 parts of concentrated sulfuric acid, 0.05-0.3 part of ammonium molybdate, 0.1-0.2 part of ammonium acetate, 0.5-1 part of sodium benzoate and 70-80 parts of deionized water. The preparation method comprises the following steps: a. mixing ethylenediaminetetraacetic acid disodium salt, calcium chloride, ammonium molybdate, ammonium acetate and deionized water to be uniform according to the weight parts; b. adding sodium benzoate and carzenide into a substance A according to the weight parts; and c. adding concentrated sulfuric acid into a substance B. With the adoption of the carbon monoxide detection reagent prepared by the invention, the concentration of carbon monoxide can be rapidly detected, the detection reagent is easy and convenient to operate and convenient to carry, and color developing agents can be recycled.

Description

technical field [0001] The invention belongs to the technical field of analytical chemistry, and in particular relates to a carbon monoxide detection reagent and a preparation method thereof. Background technique [0002] Pure carbon monoxide is a colorless, odorless, non-irritating gas under standard conditions. The relative molecular mass is 28.01, the density is 1.3g / L, the freezing point is -207°C, and the boiling point is -190°C. The solubility in water is very low, and it is extremely difficult to dissolve in water. The explosion limit of air mixture is 12.5%-74%. After carbon monoxide enters the human body, it is very easy to combine with hemoglobin in the blood to produce carboxyhemoglobin, which prevents hemoglobin from combining with oxygen, makes hemoglobin lose its ability and function to carry oxygen, and causes tissue suffocation. It has toxic effects on tissue cells throughout the body, especially the cerebral cortex. By the time people realize carbon mono...
