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

Abstract

We carried out this study in order to reduce pollution rates by treating the water produced from dyeing operations using reactive dyes, by removing the color from the liquid wastes of yellow 145 using two different types of slag-based geopolymer. The factors affecting the decolorization were optimized according to various parameters such as the dose of adsorbents, treatment time, at different pH and dose of the dye used.
