[Iron Man 2] How did Tony get cured of the palladium poisoning?

Starting off yes he got a new core for the arc reactor which stopped further palladium poisoning and prevented his condition from getting worse. 

What I'm asking is how he got rid of the rest of the palladium in his bloodstream? Its still extremely toxic and as far as I remember there wasn't anything shown to purge it from his system?

His natural processes would purge it from his system. It'd get cleared out of his blood via the liver, through the kidneys, and then peed out, same as any other metal. It was the continuous infiltration of *new* palladium coming from the reactor cores that was putting him in a bad state, keeping his overall levels too high for health and wellness.
