Spectrophotometric Analysis of Some Reactive Azo Dyes Used in Texile Industuries

Poonam Gupta, Siddhartha Barun, Shikha Roy

Abstract :

 In the present study absorption maxima (λmax) and absorption spectrum of six textile reactive azo dyes were studied. The absorption maxima (visible range) for the various dyes obtained were: – Red–5B (512 nm), Orange–3R (492 nm), Yellow–GR (415 nm), Black–B (597 nm), Turquoise Blue–G (661 nm) and Blue–3R (666nm). During the absorption spectrum study multiple peaks were obtained, in UV as well as Visible range. All the dyes were showing multiple peaks in UV range and single peak in the visible range except Turquoise Blue–G and Blue–3R. This study provides some information regarding structure of the relatively less studied dyes and could be utilized to follow the course of dye degradation by the microbial cultures.
