group attachment site and identity of the acidicfunction. In general, the lariat ether hydroxamic acids were more efficient and selective lanthanideion extractants than the corresponding lariat ether carboxylic acids. The 1H nmr and ir binding studies indicate that both the macrocyclic polyether unit and the proton-ionizable group are involved in lanthanideion complexation.
