The main component of deoxidizers is usually a reducing agent rather than an oxidizing agent.
Reducing agents refer to a type of chemical substance that can remove oxygen atoms from oxygen molecules in other substances, thereby reducing the concentration of oxygen in the environment. They can capture oxygen atoms in oxygen molecules in chemical reactions, causing them to react with reducing agents and form relatively stable products.
Common reducing agents include sulfur dioxide, sulfite, hydrogen gas, ferrous sulfate, etc. These reducing agents can react with oxygen to reduce oxygen atoms in oxygen molecules to water or other compounds, achieving the effect of removing oxygen.
It is worth noting that although oxidants can also participate in deoxygenation reactions in certain situations, in general deoxygenators, reducing agents are mainly used to eliminate oxygen. Therefore, if deoxygenation is required, chemical substances with reducing properties are typically used as deoxidizers.
