How To Neutralize Hydrogen Sulfide Gas
The method of removing hydrogen sulfide
Hydrogen sulfide is smelly and poisonous, and it is harmful to people and things. Therefore, the method of going away must be investigated.
To remove hydrogen sulfide, the first method of chemical neutralization is proposed. Alkali can be prepared, such as the genus of sodium hydroxide. Hydrogen sulfide can form salt and water when it encounters alkali. This is the principle of acid-base neutralization. Take sodium hydroxide as an example, it is phased with hydrogen sulfide to form sodium sulfide and water. Its formula is: $H_ {2} S + 2NaOH\ longrightarrow Na_ {2} S + 2H_ {2} O $. When doing this operation, pay attention to protection, because hydrogen sulfide is toxic and alkali is also corrosive.
There is another method of oxidation. Strong oxidants can be used, such as hydrogen peroxide. Hydrogen peroxide encounters hydrogen sulfide and can oxidize it into sulfur elemental matter and water. Its formula is: $H_ {2} S + H_ {2} O_ {2}\ longrightarrow S + 2H_ {2} O $. This process is relatively clean and the product is less contaminated. However, hydrogen peroxide also needs to be properly stored to prevent danger.
In addition, the adsorption method is also feasible. Choose an adsorbent such as activated carbon, and hydrogen sulfide can be attached to it. Activated carbon has a wide number of pores, a wide surface area, and strong adsorption force. When used, hydrogen sulfide can be fully contacted with activated carbon to make its best.
All these methods have their own advantages and disadvantages. Those who do it should choose the best according to the facts, in order to remove hydrogen sulfide, clean the environment, and ensure the safety of people and animals.
