I asked a question regarding oxygen meters recently in another section of the forum but unfortunately no one seems to have used them before. So I thought I would break the problem down and ask a direct chemistry question... If I introduce phenol to a water solution will there be any reaction occurring that would effect the oxygen content? Further, if I degas the solution how would the presence of phenol effect the solutions ability to "hold" the oxygen in the solution? Thanks for any ideas, I can't seem to find any data on this on the internet.
