摘要： 稀土的乙酰丙酮络合物的研究已有80多年的历史。三价稀土离子与乙酰丙酮形成络合物的稳定常数早巳系统地测定过[1]。但是,二价稀土离子,例如铕(Ⅱ)与乙酰丙酮形成络合物的稳定常数未见报道。本文叙述试用pH法测定乙酰丙酮铕(Ⅱ)的稳定常数。

Abstract: This paper describes the determination of stability constants of Eu(acac )2 by pHmethpd in N2 at t=l5℃ and  (NaClO4), with the results as follows: K1 = 1.78×105, K2 = 93.
