Thermodynamic characteristics of metal cations interaction with diethylenetriamin and its derivatives in water solution
Thermodynamic characteristics of interaction of calcium, zinc, copper and iron nitrates with diethylenetriamine (DETA) and diethylenetriaminpentamethylphosphonic acid in a water solution at 298 K and the ionic strength of 0.1 were determined by calorimetric and potentiometric methods. The comparison of thermodynamic values of the specified ions bonding with DETA and its methylphosphonic and methylcarboxylic derivatives has been carried out.
