Overview

Batch adsorption reveals optimal lead removal efficiencies in aqueous solutions using corn husk, indicating effective chemisorption.

Key Points

  • Lead removal efficiency improved with increased corn husk dosage, achieving maximum removals of 96% at 1.5 g/L dosage.
  • Optimal contact time for lead adsorption reached equilibrium at 105 minutes, showing effective kinetics for corn husk usage.
  • Isotherm analysis identified the Langmuir model as best fitting, indicating monolayer adsorption capacities from 85 mg/g to 178.57 mg/g.
  • Kinetic studies confirmed pseudo-second-order model's accuracy, underscoring the role of chemisorption in lead removal efficiency.
