Overview

This research demonstrates effective dye removal using activated carbon biosorbent from Catha edulis, indicating its potential for textile wastewater treatment.

Key Points

  • The activated carbon from Catha edulis stem achieved a maximum dye removal efficiency of 94.5%.
  • Under optimal conditions of pH 3.05 and contact time of 38.79 minutes, the dye removal was assessed.
  • Batch adsorption experiments confirmed the fit of equilibrium data to the Langmuir isotherm model.
  • The study suggests that activated carbon from agricultural waste could provide an affordable solution for textile wastewater treatment.
