DECOLORIZATION OF TEXTILE DYES BY FENTON REAGENT

HA. Modi A.H. Modi and SA. Bhatt

Abstract

All the seven textile dyes used in the study were decolorized by non-enzymatic classical Fenton reagent, Fe(II) and hydrogen peroxide. Remazol magenta HB(69.6%),Remazol red H8B (85.5%), Reactive orange 13 (74.9%), Reactive black 5(90.6%) and Remazol brilliant blue R (92.9%) were intensively decolorized by Fenton reagent within 30 minutes. Decolorization of Reactive blue 21 and Reactive'brown 18 was achieved only to 50% by Fenton reagent.The use of hydroxyl radical scavenger completely inhibited decolorization confirming the involvement of hydroxyl radical in decolorization reaction by Fenton reagent.
