Okay, so I had a pretty bad accident a while back, regarding some unfortunate chemistry that was never supposed to mix. The mistake itself was pretty easy to make, but reversing it is something I never thought possible and completely forgot about for god knows how many months.

Is there a way to remove ammonia from amphetamine-sulphate? The entire batch is now a soup instead of a salt, in a ratio about 1:3. Is there any way to purify the sulphate in a few, maybe even non-time consuming manner? Preferrably fewer than five steps, but I understand this may not be the easiest task to perform.

Thanks for any answers, discussions and comments.
