• 中文摘要： 本文係以質量作用定律為基礎,以三種不同的方法(計量法、錯合法及Meissner法)分析DBBP自氯化鹽濃溶液中萃取鋅離子之分配平衡數據。結果發現,應用Meissner法以估計電解質水溶液活性係數之熱力學分析法能成功地描述這個萃取系統。此外,本文亦求出298K下相關反應之熱力學平衡常數及萃取劑DBBP在有機溶劑中之二聚化常數。
• 英文摘要： In this paper, the distribution data were thermodynamically analyzed for the extraction of zinc(II) from relatively concentrated chloride solutions with di-.pi.-butyl butylphosphonate (DBBP) on the basis of the law of mass action. A method employing the Meissner equations for stoichiometric activity coefficient estimations was found to be effective for the explanation of the distribution data. The thermodynamic equilibrium constant for the extraction reaction was determined and the dimerization (self-association) constant of DBBP was also estimated at 298K.
