ABSTRACT:
The invention disclosed relates to an agent capable of selectively binding lithium ions to form a lithium complex, employed in association with a biologically inert carrier or excipient. Typically, the agent is included in a novel graft polymer, such as a cross-linked polystyrene polymer. This invention may also be applied to sensing lithium ion concentrations in aqueous solution and to the selective removal of lithium ions from an aqueous solution, including biological fluids.
