Deoxigénezált

Deoxigénezált is a Hungarian term that translates to "deoxygenated" in English. It describes a state where a substance, typically a liquid or gas, has had oxygen removed or significantly reduced. This process is important in various scientific and industrial applications.

In chemistry, deoxygenation is often employed to prevent unwanted oxidation reactions. For example, certain solvents are deoxygenated before use in sensitive organic synthesis to avoid reactions with dissolved oxygen that could lead to impurities or reduced yields. Inert gases like nitrogen or argon are commonly used to displace oxygen from solutions or reaction vessels.

In environmental science, deoxygenated water, often referred to as anoxic or hypoxic conditions, can be a significant issue. This occurs when the concentration of dissolved oxygen in a body of water drops to levels that cannot support aquatic life. Causes include eutrophication, where excessive nutrients lead to algal blooms that consume oxygen when they decompose, and thermal pollution, where warm water holds less dissolved oxygen. This can lead to fish kills and a disruption of the aquatic ecosystem.

Industrially, deoxygenation is crucial in boiler feedwater treatment to prevent corrosion. Dissolved oxygen in water can react with metals like iron and steel, leading to the formation of rust and degradation of equipment. Deaerators are commonly used to remove dissolved gases, including oxygen, from boiler feedwater before it enters the system. The term deoxigénezált therefore signifies the absence or reduction of oxygen, a condition sought after or occurring in specific contexts for chemical stability, environmental health, or industrial process integrity.
