The interaction between trans-1,2-diaminocyclohexane-N, N, N', N'-tetraacetic acid (H1DCTA 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°C, 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°C. 相似文献
