Abstract: The work aims at adsorption studies of nickel from aqueous solution onto activated nano carbon prepared from Syringodium Isoetifolium Leaves, by acid treatment was tested for its efficiency in removing nickel ion. The process parameters studied include agitation time, initial nickel ion concentration, adsorbent dose, pH and temperature. The adsorption followed second order reaction equation and the rate is mainly controlled by intra-particle diffusion. The equilibrium adsorption data were correlated with Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Hurkins-Jura, Halsay, Redlich-Peterson, Jovanovich and BET isotherm models. The adsorption capacity (Qm) obtained from the Langmuir isotherm plot at an initial pH of 6.5 and at 30, 40, 50, 60 ± 0.5 0C. The influence of pH on nickel ions removal was significant and the adsorption was increased with increase in temperature. A portion of the nickel ion was recovered from the spent ASI-NC using 0.1M HCl.
