What does deoxygenize mean?
Deoxygenize means to remove oxygen from a substance, system, or enclosed space. Its clearest use is transitive, as when a water-treatment process removes dissolved oxygen or a controlled atmosphere is prepared for manufacturing and laboratory work. The word can also be used intransitively, describing a substance or environment that loses oxygen. Deoxygenization is distinct from simply removing air or every dissolved gas because it identifies oxygen as the specific substance being eliminated. The term is especially useful in discussions of water chemistry, corrosion prevention, metallurgy, medicine, and controlled industrial environments, where even small changes in oxygen concentration can affect safety or product quality. Although its meaning is relatively transparent, the word conveys technical precision and is not usually chosen for informal descriptions of opening a container or allowing air to escape. It belongs to the wider scientific vocabulary formed from oxygen and related derivatives such as oxide, oxidation, and oxidize.

Deoxygenizing is more precise than simply removing air: oxygen is the specific target.

Where does deoxygenize come from?
Deoxygenize is an English formation combining the prefix de-, the noun oxygen, and the verbal suffix -ize, with the overall sense of taking oxygen away. It belongs to the same developing scientific vocabulary as deoxygenate and other oxygen-related formations. The element oxygen comes ultimately from Greek oxys, meaning “sharp,” together with a root meaning “producing,” originally referring to acid-forming substances.
