Removing dissolved organics from ammonia solution


Yesterday I noticed that my bottle of ammonia had turned white and become stiff. I transferred to to a glass bottle. But the issue now is that the ammonia contains some of the dissolved plastic. How would I remove the plastic contaminants from the ammonia? Obviously I can't just distill it, as the ammonia will all come out of solution before the water boils, so how else would I purify it? Or is it just not worth it, and I should throw it out and make some new ammonia from fertilizer?

Thanks!

Edit - I should mention, it's about 400ml of 25% ammonia solution

Nuclear physics is neat. It's a shame it's so regulated...

Now that I think about it, that's probably a good thing. Still annoying though.

reflux the solution, put a tube from the top of the condenser to a suckback trap and then so it bubbles into a vessel of water. The ammonia will be driven out by the high temperature and it will redissolve in the fresh water (use aprox 300ml, ice cold)

Thanks! I'll do that. So I assume I'll loose around a quarter of the ammonia, given it will redissolve in only 300ml?

Edit - wait no, I'm stupid, the ammonia makes up 25% of the volume

Just use the same amount of water and you should end up with roughly the same concentration.
