Abstract
The chelating agent, o-phenylene-dinitrilo-tetraacetic acid, has been synthesized, by a method previously reported, and characterized. The formation constants for the reactions between a group of divalent metal ions and the chelon, o-phenylene-dinitrilo-tetraacetic acid, have been determined potentiometrically with a mercury electrode. The stability constants for the metal ions Hg2+, Mg2+, Mn2+, Zn2+, Co2+, Cd2+, and Pb2+ were determined. Log K values of 18.6, 7.2, 11.8, 13.3, 13.4, 13.7, and 14.1, respectively, were found at an ionic strength of 0.1 and 25°C. These stability constants were compared to those of ethylene-dinitrilo-tetraacetic acid chelate. Some of the effects of ligand structure on metal chelate stability were discussed.
