  ABSTRACT: Water contamination by Remazol® dyes can be remediated with the use of bleaching metal complexes. In this study, a series of Mn(III) complexes and ferric nitrilotriacetate were found to be useful in the degrada-tion of Remazol Blue, Remazol Turquoise and Remazol Brilliant Blue. The effect of peroxide, pH, time and irradiation on the bleaching of the dyes was studied. Mn(III)-salen complexes were effective in the degrada-tion of the diazo Remazol Blue dye in the presence of a 2-fold excess of hydrogen peroxide. This dye was also effectively bleached by a combination of hydrogen peroxide, ferric nitrilotriacetate and light irradiation. This is the first time well-defined, low molecular weight trivalent metal complexes are applied to the degra-dation of Remazol® dyes.
