Complexing molecules? E.g. EDTA, crown ethers, paracyclophanes or cyclodextrins (they are available in different sizes for different metals) If you search for the key words you find tons of refs.

Mahmood Sanei

EDTA is a best complexing agent for these metals but extracting them is difficult. Insoluble salts is a other method for extracting them.
