Co-extraction of Lanthanoid(III) with Various Metal Ions in the Chelate Extraction System with Acetylacetone
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 bet...

| Summary: | 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. |
