    High performance magnetic separation of gold

    First published on 29th October 2009. We present the magnetic separation approach to facilitate the recovery of gold nanoparticle AuNP catalysts.The use of magnetically recoverable supports for the immobilization of AuNPs instead of traditional oxides polymers or carbon based solids guarantees facile clean fast and efficient separation of the catalyst at the end of the reaction cycle.

    Shawn - Pure gold is not magnetic. That is it doesnt form a magnet on its own. If you put it in a magnetic field it will magnetize a tiny bit but only so long as its in the field. and the direction of the magnetizaqtion makes it weakly repel the magnet. There are alloys of gold for example gold with more than about 20 of the atoms replaced by iron which do magnetize on their own at .
