Hydrogen Sulfide Detection
On the method of detecting hydrogen sulfide
The detection of objects in the world, the techniques are complicated and simple, and the methods are different. For the detection of hydrogen sulfide, it is particularly important. Those who cover hydrogen sulfide have different colors and odors, and their sex is toxic, which is related to people's livelihood and material use. Therefore, the method of testing must be carefully studied.
Those who tested hydrogen sulfide in ancient times often tested it with objects. There are silverware, which is placed in the environment containing hydrogen sulfide, and at a little bit, the silver gradually turns black. This is because it is combined with sulfur in hydrogen sulfide to produce silver sulfide. There are also wet lead acetate test papers. If the paper turns brown and black, it is known that there is hydrogen sulfide. When lead acetate meets hydrogen sulfide, it synthesizes lead sulfide, and its color is black.
Today's technology is new, and the method of detecting hydrogen sulfide is more refined. There are instruments designed to accurately measure its concentration. The instrument of gas chromatography can analyze the amount of hydrogen sulfide in the mixed gas. With its separation and identification, the amount of hydrogen sulfide can be known. There are also electrochemical sensors, which are sensitive to gas changes and respond to electrical signs. They can show the degree of hydrogen sulfide in real time, which is convenient and efficient.
However, regardless of the ancient method or technology, when using it, you should be cautious. Although the ancient method is simple, the situation is complicated or inaccurate. Today's instruments, although fine, must also be well protected and used, otherwise, there is a risk of mismeasurement. Therefore, in order to obtain the true state of hydrogen sulfide, we must be rigorous and make good use of various methods in order to be correct.
