Decolorization of Reactive Dyes, Part VI: Eco-Friendly Approach of Reactive Dye Effluents Decolorization Using Geopolymer Cement Based on Metakaolin backed by slag

In order to reduce pollution and preserve the environment, we conducted this study to remove the color from the dyeing baths residues from the liquid waste of reactive yellow dye 145, using two different types of geopolymer based on metakaolin or metakaolin mixed with slag by 70 to 30%, and the results showed that this method promising color reduction as an inexpensive and economical method
