邻羟基苄胺-N,N,O-三乙酸(HBATA)及其络合物的研究(V)——萃取法测定La^(3+),Nd^(3+),Eu^(3+),Yb^(3+)与HBATA的络合物稳定常数

STUDIES ON o-HYDROXYBENZYLAMINE-N,N,O-TRIACETIC ACID(HBATA) AND ITS COMPLEXES(V)——DETERMINATION OF STABILITY CONSTANTS OF La^(3+), Nd^(3+), Eu^(3+), AND Yb^(3+) COMPLEXES BY SOLVENT EXTRACTION

以1-苯基-3-甲基-4-苯甲酰基吡唑酮-5为萃取剂,用溶剂萃取法测定了水溶液中HBATA与La^(3+),Nd^(3+),Eu^(3+),Yb^(3+)生成的络合物稳定常数。

Complexes of La^(3+), Nd^(3+), Eu^(3+), and Yb^(3+) with HBATA in aqueous solution have been studied by the method of solvent extraction with PMBP as extractor. The stability constants of these complexes have been determined.
