Synergistic Extraction of Lanthanum with 1,9-Bis (1' -Phenyl-3' -Methyl-5' -Oxopyrazol-4' -yl) -1,9-Nonanedione and1,10-Phenanthroline or 2,2'-Bipyridyl

Abstract

Abstract: 1, 9-bis( 1'-phenyl-3'-methyr-5'-oxopyrazol-4'-y1)-1, 9-nonanedione (H₂A) was one of a series of bis acyl pyrazolone chelate extractants synthesized recently. In this paper, single and synergistic extraction by H₂A and 1,10-phenanthroline or 2,2'-bipyridyl(simplified as B) for lanthanum from aqueous nitric acid or nitric acid and sodium acetate buffer have been investigated, respectively. By using slope analysis method the formulas of the extracted complexes have shown to be LaA· HA·B and the extraction equlibrium constants have been calculated. The values of the equlibrium constants (1gβ₂₈₁) of LaA·HA·Bshow large synergistic effect. The solid extracted complexes were isolated from the solution. The compounds were studied by elemental analysis,TG-DTA, UV, IR,¹HNMR and the solubility in chloroform was determined.

Key words: Synergistic extraction, Bis acyl pyrazolone, Lanthanum, Extracted complex
