The present paper aims at the difficulty in separation and pre-concentration of rare-earth elements.Erbium(Ⅲ)-ion imprinted silica gel(Er-IISG)sorbent was synthesized by surface imprinting technique and was employed as a selective solid-phase extraction material for determination of Er(Ⅲ) from other lanthanide ions.The higher selectivity coefficient of Er-IISG for Er(Ⅲ) in the presence of competive ions such as Tb(Ⅲ),Dy(Ⅲ) and Tm(Ⅲ) was above 390,which was 42 times over non-ion imprinted silica gel(NISG).The static adsorption capacity was 58.01mg/g.The Er-IISG offered a fast kinetics for the adsorption and desorption of Er(Ⅲ).The developed method was rapid,selective,sensitive and applicable to the determination of trace Er(Ⅲ) in environmental samples with complicated matrix.
