Abstract

Our strategy, which we developed a decade ago, aims to reduce pollution rates by treating the water generated from the dyeing process. Here we did the same study but using reactive dyes, by decolorizing red effluent 195 using two different types of geopolymer based on metakaolin. The factors affecting decolorization were studied such as the adsorbent dose, duration, different pH and finally the dose of dye used
