Hi all,
I have a student that wants to study persulfate digestion through measurement of evolved O2. For mixing model calculations to describe the final products, she would like to measure 18O of persulfate and NaOH in solid form. I am particularly concerned with the sodium hydroxide due to its caustic nature.
Has anyone analyzed either of these compounds via pyrolysis? I’m concerned that there may be some detrimental effects on my hardware, although I will probably only analyze 4-5 samples of each.
Is there some sort of trap I could install to remove basic compounds? Can anyone think of any precautions or other concerns?
Thanks for your help,
Ben
