Abstract: Ten thallium(I) ion PVC membrane electrodes based on eight saturated urushiol crownethers were prepared.Electrodes of no.1 and 4 appeared the best ones their comprehensiveproperties.They exhibited linear responses in 4×10-7~5×10-1 and 8×10-7~1×10-1mol/L TlNO3, respectively.The electrodes showed a higher selectivity to K ion than othercrown ether Tl(I) electrodes reported in the literature.

Key words: urushiol, crown ether, thallium, ion selective electrode
