Testing Hydrogen Sulfide in Air
The method of testing hydrogen sulfide in the air
To test hydrogen sulfide in the air, there are various ways. First, chemical reagents can be used. Take lead acetate test paper, if the air contains hydrogen sulfide, the test paper will turn from white to brown black. This is because hydrogen sulfide reacts with lead acetate to produce lead sulfide.
Second, it can be detected by means of an instrument. Gas chromatograph can accurately measure the content of hydrogen sulfide in the air. Its principle is to use different substances to separate in a chromatographic column and sense it by the detector to obtain the specific value of hydrogen sulfide.
In addition, there is also a portable hydrogen sulfide detector. It is small and convenient, and can display the concentration of hydrogen sulfide in the air in real time. When the concentration exceeds the set threshold, an audible and visual alarm will be issued to remind people of the dangers of hydrogen sulfide in the environment.
Test the hydrogen sulfide in the air, and choose the appropriate method according to the actual situation to ensure accurate and efficient detection.
