This study created green multifunctional geopolymeric sorbent material with strong cationic dye adsorption capacity and superior mechanical strength to broaden lead sludge (LS)-based geopolymer applications. In this study, two sorbents (Go G) were fabricated using slag blended 0 50 wt.% LS, respectively activated 6 NaOH. The Go G specimens normally cured for up 28 days, while hydrothermally at different steam-pressures modify/improve histological characteristics as well resistance. selected characterized via XRD, FTIR, TGA/DTG, XPS, N2-adsorption/desorption SEM/EDX techniques. G/5bar's high may be due the production of CSH, CAH, CASH, NASH, which formed a fine mesoporous zeolitic structure highest BET-surface area (64.55m2/g) lowest BJH-maximum pore diameter (9.68nm). maximum MB synthesized adsorbent was 230.4 mg/g.

Abstract Crystal violet (CV), a widely used dye in paints and textiles, poses significant environmental threat due to its non-biodegradable nature. A modified slag-based geopolymer has been developed address this issue by incorporating raw moringa seed powder (MSP), an agricultural waste. The geopolymers (SM1, SM2, SM3) were created adding different percentages of MSP (0.2%, 0.6%, 1% weight) ground granulated blast furnace slag (GGBFS), using sodium silicate 10 M hydroxide as alkali activators. This combination enhances the geopolymer’s mechanical adsorbent properties, making it more effective for CV removal. composites analyzed X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). Their properties evaluated conducting compressive strength total porosity tests. Pore structure analysis was performed nitrogen adsorption desorption techniques, point zero charges determined. Additionally, batch experiments carried out investigate dye, employing two isotherm models kinetic analysis. SM1 mix, which is containing 0.2% MSP, exhibited highest at 73 MPa after 180 days, representing 25.8% improvement compared control mix (100% slag). Furthermore, mixes showed greater activity toward crystal with SM3 achieving capacity up 322.58 mg/g. study demonstrates that capacity. indicates positive impact on composite’s surface highlights benefits utilizing industrial waste wastewater treatment.
