Noncovalent surface grafting of uranium complexed cucurbit[5]uril oligomer onto palm shell powder: a novel approach for selective uranyl ion extraction.

Biomass - that is a new feather in your cap: palm shell powder was used as support for novel uranyl complexed cucurbit[5]uril oligomer to obtain a selective extractant for uranium. The key to the selectivity lies in the perfect environment of the two portals of cucurbit[5]uril for uranyl ion binding.
