Abstract
In this study, the color removal performance of polyamidoamine (PAMAM) dendrimer was examined in real reactive dyeing bath wastewater (that is, waste water in which the dye is in hydrolyzed form and contains other auxiliary chemicals used in dyeing besides the dye). These experiments were carried out on three reactive dye bath wastewaters, one for trichromatic light color, one for trichromatic dark color, and one for turquoise color dyeing, supplied from a dyehouse. Studies conducted on real plant dyeing wastewater showed that the optimum conditions were 50-100 mg/L dendrimer and 15-30 minutes centrifugation. Color removal efficiency was between 75-90%. In the light of all these results, it can be said that dendrimer technology can be an alternative to other existing techniques in decolorizing reactive dye bath wastewater.
