• Co extraction of Lanthanoid 3 with Various Metal Ions in the Chelate Extraction System with Acetylacetone

Abstract

The co-extraction phenomenon was found in a typical chelate extraction system, in which the extraction of lanthanoid ion (Ln³⁺) with acetylacetone (Hacac) was highly enhanced by various metal ions (Mⁿ⁺) such as Cu²⁺, Al³⁺, and Zr⁴⁺. This phenomenon was ascribed to the formation of the 1:1 adduct between Ln(acac)₃ and the M(acac)_n extracted into the organic phase. The co-extraction occurred more readily for La³⁺ than that for Lu³⁺, and increased in the order of Cu²⁺ < Al³⁺ < Zr⁴⁺. This work elucidated that the co-extraction due to the adduct formation is a rather common phenomenon in the chelate extraction.
