摘要：
In this study, the adsorption potential of activated carbon for removal of Ni2+ ions from wastewater has been investigated. The study involves batch type experiments to investigate the effect of initial concentration, adsorbent dose, agitation speed, contact time, temperature and pH of the solution in adsorption process and the optimum conditions were evaluated. The adsorption process has fit pseudo-second order kinetic models. Langmuir and Freundlich adsorption isotherm models were applied to analyze adsorption data and both were found to be applicable to this adsorption process. Thermodynamic parameters, e.g., Delta G degrees, Delta S degrees and Delta H degrees of the on-going adsorption process have also been calculated and the sorption process was found to be endothermic
