Abstract: The complexes of rare earth (Ln = La~Nd)with saturated urushiol crown ether (DSU30C10) have been synthesized in acetonitrile solution. The complexes have been characterized by elemental analysis, IR and UV spectra, molar conductance and differential thermal analysis,The lanthanutn iOn selective electrode with saturated urushiol crown ether as a neutral carrier exhibited linear responses in 1×10-2~1×10-6mol/L La(NO3)3. The electrode showed better selectivity than other La(Ⅲ)electrodes reported in literature。

Key words: urushiol, crown ether, rare earth complex, ion selective electrode
