Abstract

The adsorption of lanthanide(III) ions by the glutathione-(α-L-glutamyl-L-cysteinyl-glycnei, GSH) monolayer on gold substrate (GSH/Au) is described and demonstrated for the recovery of lanthanide(III). This monolayer has been applied to the adsorption of lanthanide(III) ions in aqueous solutions as an adsorbent. The pH dependencies of the adsorption for lanthanide(III) ions have been examined to clarify the cation-exchange behavior of the adsorbent. Adsorption of lanthanide(III) ions was found to depend on the pH of the solution. The adsorption recovery for the 14 lanthanide(III) ions was investigated.
