A suggested approach for handling reactive organic dye waste from the textile industry was developed using the geopolymerization process. Two separate kinds of geopolymer cement pastes are used to reduce the colour of the liquid wastes of reactive yellow 145. According to the results, we were able to cleanse the water created by dyeing processes and lower pollution rates. Geopolymer cement pastes were organized using metakaolin and slag as an aluminosilicate source separately, sodium silicate and sodium hydroxide as an alkali activator in the presence of organic dye pollutant reactive yellow 145. The study was carried out with various PH mediums and hydration times. Spectrophotometric measurements were used to measure the % leaching of pollutant dye. The % leaching of reactive dye was examined with variable pH (0.1M NaOH, deionized water and 0.1M HCl). We also examine the effect of reactive dye on the hydration characteristics of different geopolymer mixes. FTIR and XRD studies were employed to evaluate the influence of the reactive dye's incorporation inside GP samples.

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.
