Effect of Process Factors on the Adsorption of MB Dye Using Adenia Lobata Fiber

This study was undertaken to investigate the adsorptive capacity of Adenia lobata fiber on MB dye. The experiments were carried out in a batch system to study the effects of adsorbent dosage, MB dye initial concentrations, PH, and contact time on the adsorptive capacity of the activated carbon fiber. The scanning electronic microscopy (SEM) revealed well pronounced porosity which indicated good possibility for the dye to be trapped and adsorbed. PH did not have much effect on the removal efficiency, the removal efficiency slightly increased as pH was increased from 2 to 10. The removal efficiency increased with the increase in dosage of the adsorbent while the adsorptive capacity decreased. The increase in initial concentration increased the adsorptive capacity but decreased the removal efficiency. The equilibrium adsorption data fitted well with intraparticle diffusion model but was not the only rate controlling step; boundary layer diffusion controls it to some extent. The thermodynamic parameters indicated the process as feasible and spontaneous. The process was endothermic at lower initial concentration and exothermic at higher initial concentration.
