Decolorization of Reactive Dyes, Part VII: Eco-Friendly Approach of Reactive Dye Effluents Decolorization Using Geopolymer Cement Based on Metakaolin-Slag mixes

Using two different types of geopolymers based on metakaolin-slag mixes by 80 to 20% and 60 to 40%, we did this investigation to remove the color from the dyeing bath residues from the liquid waste of reactive yellow dye 145 in an effort to reduce pollution and preserve the environment. The findings demonstrated that this technique offered colour reduction and environmental safety.
