Decolorization of Reactive Dyes, Part IX: Eco-Friendly Approach of Reactive Red 195 Dye Effluents Decolorization Using Geopolymer Cement Based on Metakaolin-Slag Mixes

In the light of our strategy based on reducing pollution and protecting the environment, and as a continuation of our previous work, we conducted this study to remove the color from the residues of the dyeing bath from the liquid waste of Reactive Red 195 using two different types of geopolymers based on metakaolin-slag mixtures in a ratio of 4 : 1 and 3 : 2. The results showed that this method gave environmental safety and colour reduction.
