Dear all:

I may need to deoxygenate solvents and some aqueous solutions to determine
the conten o fhydroperoxides in my samples by purging with nitrogen.
I have read that 30 min is suitable for volumes of 50-100 mL of some
solvents. However, there are many factors affecting the removal of oxygen,
and both the conssumption of nitrogen and the loss of solvents may be
significant.
Therefore, I am interestined in finding if there is any kinetic study
concerning deoxygenation of different systems or alternatively if there any
easy and cheap method to control the amount of residual oxygen that is left.

Thanks in advance,

Juan
