The phrase "affinity for oxygen" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly when discussing the attraction or preference of a substance or organism for oxygen.
Example: "Hemoglobin has a high affinity for oxygen, allowing it to effectively transport oxygen throughout the body."
Alternatives: "preference for oxygen" or "attraction to oxygen".
Perfluorocarbon solutions (PFCs) are biochemically inert organic compounds with a high affinity for oxygen and CO2 that can improve tissue oxygenation when used with high inspiratory concentrations of oxygen [1].
However, it has since been shown that oxygenated neuroglobin undergoes rapid autoxidation and has a relatively low binding affinity for oxygen [ 37, 41].
This strong affinity for oxygen and other gases accounts for its use as a getter for removing residual gases in electron tubes.
Converter-produced blister copper and blast-furnace lead also are treated by fire refining, with both processes depending on the weaker affinity for oxygen of the metals than the impurities they contain.
In oxidation, metals having a great affinity for oxygen selectively combine with it to form metallic oxides; these can be treated further in order to obtain a pure metal or can be separated and discarded as a waste product.
Nitrosomonas europaea has higher affinity for oxygen than does N. oligotropha (Park and Noguera 2007).
Fetal hemoglobin's affinity for oxygen is substantially greater than that of adult hemoglobin.
However, these alloys have great affinity for oxygen and other chemical oxidizing agents.
Cerebral tryptophan hydroxylase appears to have a poor affinity for oxygen and to be affected by slight hypoxia.
Pure titanium has a high affinity for oxygen, but Ti-6Al-4V undergoes a process called self-passivation to create a protective film that can resist corrosion.
This shows that an oxygen layer is present, which is consistent with titanium having a higher affinity for oxygen than nickel.
