Abstract

Formation of 1: 1 adduct intermediates was detected between peroxomonosulfate ion and tris-(2, 2'-bipyridine)iron(II) or tris-(1, 10-phenanthroline)iron(II) complexes. The formation equilibrium constants were determined (27 3 and 63 18 (mol L-1)-1) on the basis of kinetic measurements. The adduct was also detected by ESI mass spectrometry with the phenanthroline complex. A mechanism for the oxidation of tris-(2, 2'-bipyridine)iron(II) or tris-(1, 10-phenanthroline)iron(II) by peroxomonosulfate ion is proposed.
