Whether or not you can get away from using perchloric (and HF for that matter) will depend on what your researcher intends to do with the hydrolyzed fat.
The book Prudent Practices in the Laboratory has an LCSS for this acid, which does describe clean-up. The book, can be viewed online for FREE. The PDF version is also FREE. E-book and paper formats are also available for a charge. This
is also the case for other chemical safety books in the NAP's catalog.
Here is a link to the book
Thank you,

** External Email **
Greetings everyone,
we have a researcher who will be using 70%-72% Perchloric acid, he is making a 1:1 mix with Glacial Acetic Acid for the hydrolysis of fish fats. In either case, we have some concerns with this because we do not have a perchloric acid hood
(separate issue). Now, once the mix is made, the Perchloric acid will be approximately 35% to 36%, however, my concern is with the possibility of a spill and the resulting waste from a spill. Neutralization first, yes, but then it is also recommended that
the spill NOT be absorbed with any combustible such as paper towels etc. I have thought perhaps diatomaceous earth, or a combination of neutralizer with diatomaceous earth, collect with standard non-metal dust pan then bag/tag the neutralized waste.
Does anybody have any experience with Perchloric Acid spills, neutralization and absorbents, and if so, what do you use?
thanks!
