A Sustainable Approach for Immobilization Dyeing bath Effluents of Reactive Yellow 145 by using Different Types of Eco-Friendly Geopolymer Cement

Abstract

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.

Immobilization Approach as a Creative Strategy to Remove Reactive Dye Red 195 and Cu2+ Ions from Wastewater Using Environmentally Benign Geopolymer Cement

“…The raw materials and their chemical oxide composition used to prepare slag/fly-ash-based geopolymer (SF) are the same as in our previous studies [ 20 , 22 , 34 , 38 ]. GGBFS, or ground granulated blast furnace slag, was obtained from Egyptian Iron & Steel’s Helwan Company, Cairo, Egypt.…”

“…Geopolymers have increasingly garnered a lot of attention for the immobilization of harmful wastes in recent years [ 17 ]. For the Solidification/Stablization of hazardous pollutants, which are classified into heavy metals (cations and anions) and organic pollutants, geopolymers are currently the topic of extensive several studies [ 17 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ]. Particularly geopolymers have the potential to offer extraordinarily long-term storage for the safe disposal of radioactive waste with high radioactivity [ 17 ].…”

“…Particularly geopolymers have the potential to offer extraordinarily long-term storage for the safe disposal of radioactive waste with high radioactivity [ 17 ]. The stabilization/solidification method is a unique technique that has recently been investigated for the removal of dye-contaminated water [ 34 , 36 , 38 ].…”

Decolorization of Reactive Dyes, Part VIII: Eco-Friendly Approach of Reactive Red 195 Dye Effluents Decolorization Using Geopolymer Cement Based on Metakaolin backed by slag

“…Using metakaolin-based geopolymer and slag-based geopolymer cement to remove the colour of the reactive dye that is still present in the dyeing bath was recommended by Elapaseryet al [31][32][33][34] as opposed to letting this hazardous waste go untreated. Numerous investigations have demonstrated that geopolymers with metakaolin as its main component are efficient adsorbents for a variety of water contaminants, including those containing heavy metals and dyes [35][36][37][38][39].Blast furnace slag (BFS) is made up of the inorganic, non-ferrous portions of the raw materials needed to make iron (iron ore, coal/coke, and fluxes, including limestone) that are left over after the iron is extracted from the ore [40]. The major chemical components of BFS are calcium and silica oxides, together with additional oxides like aluminium oxide and magnesium oxide, and other metallic elements including Fe, Ti, and Mn [41].…”

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

“…et al [31][32][33][34] suggested using metakaolin-based geopolymer and slag-based geopolymer cement to eliminate the colour of the reactive dye that is still present in the dyeing bath rather than leaving this hazardous waste untreated. Numerous studies have shown that geopolymers with metakaolin as their primary ingredient are effective adsorbents for a range of water pollutants, including those containing heavy metals and dyes [35][36][37][38][39][40].…”
