Turps soak for povidone. Two, maybe three non-polar boils, follow with two, three maybe acetone boils. Allow to dry. Soak in brake cleaner / dry cleaning fluid. Allow to dry. extract 3 x with MeOH, filter through sand filter, evaporate. Flash with acetone when thick enough to skin over. Let dry. Acetone boils take out the tripolidine.
Sure, takes time. Its the full treatment. It works on these pills.
Variations abound. One is three mineral spirit boils to start with, no turps soak. Some leave out the brake cleaner. Some do not flash with acetone, some recrystalize with IPA.
Some A/B the pills after some or all of the above. Some do an A/B after a turps soak and some acetone boils. Nothing else.
TFSE is full of discussions on this very subject. You should take the time to read many of the posts, particularly older posts, that are still on the boards for a reason. It will amaze you how many questions have been fully answered explored, explained, debated, and burned to death.
When using tfse, do not get in such a hurry. Read up some on how to use it. It is your best friend here. IT works. Did you search for tripolidine [and] hydrochloride? or tripolidine [or] hydrochloride. Guess which one gives up the most results?
An education is what's left when you've forgotten what you learned.
