  • Abstract

    The optimum parameters affecting the adsorption of Ni(II) using Prosopis Juliflora bark carbon (PJBC) were determined. The adsorption of Ni(II) was strongly dependent on pH, temperature and initial adsorbate concentration. The equilibrium adsorption data follows Langmuir and Freundlich isotherms. The optimum pH for Ni(II) ions removal was found out to be 5.5. The equilibrium data shows the exothermic nature of adsorption. Kinetic studies shows pseudo second order and intra-particle diffusion equations successfully describe the adsorption process.
