• 中文摘要： The interaction between trans-1, 2-diaminocyclohexane-N, N, N′, N′-tetraacetic acid (H4DCTA or H4Z) and Mn(II) and NI(II) ions has been investigated. The formation constants of the hydrogen chelates (MHZ¯), and of the normal chelates (MZ2¯), have been measured at 20, 30 and 40℃, and an ionic strength of 0.10 (KNO3). The former was done by a titration technique and the latter by a mercury indicator electrode method. Enthalpy and entropy changes characterizing the formation of the normal chelates have been calculated at 25℃.
