摘要：

This paper reports the synthesis of sulphate extractants, N,N'-bis-(2-dibutylamino-ethyl)-isophthalamide (1), pyridine-2,6-dicarboxylic acid bis-[(2-dibutylamino-ethyl)-amide] (2) and 3,4-diphenyl-1H-pyrrole-2,5-dicarboxylic acid bis-[(2-dibutylamino-ethyl)-amide] (3), and demonstrates that, in combination with a commercially available oxime extractant 2-hydroxy-5-nonyl benzaldehyde oxime (P50), these dual host systems are better extractants for nickel(II) sulphate than the metal salt extractant, 5-nonyl-3-dihexylaminomethyl-2-hydroxy-benzaldehyde oxime (4).
