Description 251-260
The present study investigates the removal of Erythrosine B (EB), a neurotoxin and carcinogenic dye from aqueous
system using Prosopisspicigera L. wood (PsLw) carbon-iron oxide composite. The adsorbent is well characterized by
Fourier Transform Infra Red spectroscopy (FTIR), Scanning Electron Microscope (SEM) for surface morphology,
Brunauer-Emmett-Teller nitrogen adsorption method (BET)/methylene blue method for surface area determination and
potentiometric methods for surface charge (pHzpc) determination. The removal capacity of the adsorbent has been evaluated
by batch method under varying pH, contact time, adsorbate initial concentrations, and in the presence of other ions. The
Langmuir maximum adsorption capacity is found to be 487.8 mg/g at pH = 2.0 for an initial concentration of 250 mg/L. The
adsorption follows pseudo second order kinetics and fits to Langmuir isotherm. The adsorption is thermodynamically
spontaneous and exothermic in nature. Pore diffusion and mass transfer studies are performed. Column mode analysis is
applied in the process for industrial applications.
