Overview

Randomized trial evaluates a new waste-based adsorbent for dye removal, suggesting a sustainable solution.

Key Points

  • This research aims to develop a geopolymer adsorbent using waste materials for the effective removal of methylene blue dye.
  • Developed geopolymer adsorbent using clay, fly ash, and GGBS.
  • Characterized adsorbent properties using XRF, XRD, IR spectroscopy, Zeta potential, BET, and EDX.
  • Conducted adsorption studies for varying concentrations of methylene blue dye.
  • Achieved over 95% dye removal efficiency for initial concentrations of 10-50 mg/L.
  • Maximum adsorption capacity determined as 21.12 mg/g for a 4 g/L dosage of B-4.
  • Adsorption kinetics best fit pseudo-first-order and pseudo-second-order models, with a fitting to the Langmuir isotherm model.
