Treatment method of sodium cyanide
Sodium cyanide is also a highly toxic substance. Its disposal is related to people's livelihood and the environment, and it should not be careless. The current treatment method is as follows.

First, oxidation method. Use a strong oxidant to react with sodium cyanide to convert it into a low-toxic or non-toxic substance. If hypochlorite is used, under suitable conditions, hypochlorite reacts with sodium cyanide to oxidize cyanogen ions into harmless substances such as carbon dioxide and nitrogen. This process requires attention to the control of reaction conditions, such as pH, temperature, etc., to ensure the efficient and safe reaction.

Second, adsorption method. Select a specific adsorbent, such as activated carbon, to use its porous structure and huge specific surface area to adsorb sodium cyanide. Activated carbon can effectively adsorb sodium cyanide on its surface, thereby reducing the concentration of sodium cyanide in the environment. However, after the adsorption is saturated, the adsorbent needs to be properly disposed to prevent secondary pollution.

Third, chemical precipitation method. Add suitable chemical reagents to react with sodium cyanide to form insoluble precipitation. For example, some metal ions can combine with cyanogen ions to form precipitation and then separate from the solution. However, this method requires precise control of the amount of reagents and reaction conditions to ensure the complete precipitation and separation effect.

When disposing of sodium cyanide, the disposal method should be carefully selected according to the actual situation, and the operating procedures should be strictly followed to achieve the purpose of safe and environmentally friendly disposal, protect the well-being of the people, and ensure the safety of the environment.
