A deoxidizer is a chemical substance used to remove oxygen from a solution. Here are some common components of deoxidizers:
Sulfite: Sulfite is a commonly used deoxidizer, including sodium sulfite, sodium bisulfite, and others. They can react chemically with oxygen, reducing it to harmless substances, effectively removing oxygen from the solution.
Combination of sulfite and alkali: This type of deoxidizer is usually composed of a mixture of sulfite and alkali (such as sodium hydroxide, potassium hydroxide, etc.). The addition of alkali can improve the activity of sulfites and enhance the deoxygenation effect.
Deoxidizers: Some deoxidizers, such as deoxyribonucleotides, deoxyglucose, etc., can also be used as deoxidizers. They can react with oxygen in the solution to form insoluble oxidation products, thereby removing oxygen from the solution.
Iron agent: Iron agents (such as divalent iron salts, trivalent iron salts, etc.) can also be used as deoxidizers. Iron agents can react with oxygen to form insoluble iron oxide precipitates, thereby removing oxygen from the solution.
It should be noted that when using deoxidizers, appropriate ones should be selected based on the actual situation and needs, and relevant operating instructions and safety regulations should be followed. During use, attention should be paid to controlling factors such as dosage, solution pH value, and reaction conditions to ensure deoxygenation effect and safety.
