Abstract

The invention discloses a carbon monoxide detecting agent and a preparation method thereof, and belongs to the technical field of gas detection. The carbon monoxide detecting agent comprises the following components in parts by weight: 15 to 50 parts of iodine pentoxide, 2 to 10 parts of hyposulphite, 2 to 5 parts of ammonium molybdate, 3 to 8 parts of concentrated nitric acid, 2 to 6 parts of yttrium nitrate, 2 to 6 parts of potassium nitrate, and 5 to 16 parts of water. The carbon monoxide detecting agent provided by the invention has the characteristics of high reaction rate and high sensitivity; a detecting method is simple; the carbon monoxide detecting agent is suitable for determining the content of CO in air in different environments.

Description

technical field [0001] The invention belongs to the technical field of gas detection, in particular to a carbon monoxide detection reagent and a preparation method thereof. Background technique [0002] Carbon monoxide (CO) is a colorless, odorless gas at room temperature, insoluble in water, difficult to liquefy and solidify, slightly lighter than air. Without consciousness, carbon monoxide can enter the human body through breathing and easily combine with oxygen-carrying hemoglobin in the blood to form stable carboxyhemoglobin. The affinity between carbon monoxide and hemoglobin is about 240-270 times that of oxygen and hemoglobin. Once carboxyhemoglobin is formed, hemoglobin loses its ability to transport oxygen, causing tissue hypoxia and tissue hypoxia. If 50% of the hemoglobin in the blood combines with carbon monoxide, it can cause myocardial necrosis. When the content of carbon monoxide in the air reaches 0.1% (volume ratio), it will cause poisoning, lead to hypox...
