Complexation of a Catecholamine with Zinc (II) in Media with Different Dielectric Constants

Abstract

The complexation of zinc (II) with dopamine has been investigated by spectrophotometric measurements in mixed solvent system at an ionic strength of 0.2 mol*dm-3 sodium chloride, employed (25± 0.1° C) at pH ranges of ~6 to ~7 with a high ratio of ligand to metal.
