You have many options including microbial siderophores (some are
sold through biosupply companies like Sigma) and the mammalian
glycoproteins transferrin and lactoferrin (very expensive). But if you are
trying to REMOVE Fe from media to create an Fe limiting environment, try
Chelex.  Works great although you'll have to add other metal ions back to
the media (Ca+2, Mg+2, etc).

Good luck
