Overview

Batch analysis demonstrates effective dye removal in aqueous solutions using modified zeolite, indicating significant potential for wastewater treatment.

Key Points

  • To investigate the adsorption characteristics of Basic Blue 41 dye using EDTA-functionalized zeolite as an effective adsorbent.
  • Performed batch adsorption experiments under varying pH, adsorbent dosage, dye concentration, and temperature.
  • Analysed adsorption kinetics using the pseudo-second-order model.
  • Evaluated isotherm data with the Langmuir model.
  • Achieved a maximum adsorption capacity of 277.8 mg/g at optimal conditions.
  • Demonstrated the highest removal efficiency at pH 9 with 0.5 g/L adsorbent dosage.
  • Confirmed that adsorption rapidly reached equilibrium within 60-90 minutes.
