How to Test for Hydrogen Sulfide
The method of measuring hydrogen sulfide
If you want to measure hydrogen sulfide, there are various methods. First, you can rely on your sense of smell. Hydrogen sulfide has the smell of rotten eggs. If you smell it in a poorly ventilated place, you may suspect that there is hydrogen sulfide. However, this is only a preliminary judgment, and you can't believe it completely. It is very toxic to cover its gas. If you smell it for too long, it will hurt your body.
Second, the chemical method. Test it with wet lead acetate test paper. If the test paper encounters hydrogen sulfide, it will turn black. This is because hydrogen sulfide reacts with lead acetate to produce lead sulfide. The reaction formula is: $H_ {2} S + Pb (CH_ {3} COO) _ {2} = PbS? + 2CH_ {3} COOH $. This test strip is convenient for field detection and is quite practical.
Third, instrument detection. There is a hydrogen sulfide detector, which can accurately measure its concentration. Such instruments are either electrochemical type or infrared absorption type. Electrochemists use chemical reactions to generate electrical signals to measure the amount of hydrogen sulfide; infrared absorbers measure their concentration according to the characteristics of hydrogen sulfide's absorption of specific infrared light. This instrument has high accuracy and is often used in industrial sites, environmental monitoring, etc., to ensure safety and protect ecology.
When measuring hydrogen sulfide, choose the method according to the scene and demand. Pay attention to safety and comprehensive protection, so as to accurately know whether it exists and how much, avoid its harm and use it for profit.
