Abstract:

In the present work, the adsorption of nickel ions from leachate sample by activated carbon prepared from seeds of Delonix Regia was studied. The activated carbon prepared by pretreatment with KOH was subjected to SEM, XRD and FTIR analysis. The influences of different experimental parameters on nickel uptake were investigated such as sorption time, final solution pH, adsorbent dosage and temperature. The experimental data were correlated to different kinetic and adsorption models and the corresponding kinetic parameters were determined. The % removal was found to be 75.03% and follows pseudo-first order kinetic model for Ni. These parameters are considered fundamental for further studies involving the scale-up of the process for continuous studies.
