Studies on the removal of nickel(II) using chemically activated pouteria sapota seed and commercially available carbon

The capacity of sulphuric acid treated Pouteria sapota seeds carbon for the removal of Nickel from aqueous solution was examined. The influence of various parameters such as effect of equilibration time, pH, and carbon dosage for the removal of Nickel was studied using batch process. The experiment demonstrated showed that equilibrium adsorption data fit the Freundlich adsorption isotherm. The adsorption behavior of the activated carbon is explained on the basis of its chemical nature. Desorption study was carried out using HCl solution with a view to regenerate the spent adsorbent and to recover the adsorbed metal ion
