Abstract
Abstract The interaction between trans -1,2-diaminocyclohexane-N,N,N′,N′-tetraacetic acid (H 4 DCTA or H 4 Z) and Th(IV) and Zr(IV) ions has been investigated potentiometrically by using a mercury indicator electrode. The formation constants of the chelates ThZ and ZrZ have been evaluated at a constant ionic strength of 0·10 (KNO 3 ) at 10, 20 and 30°C. Enthalpy and entropy changes characterizing the formation of the chelates have been calculated at 25°C. The results are collected as follows:
