摘要：

Kinetic models describing the adsorption of Ni(II) ions on to hazelnut shell active carbon (HSAC) have been compared. Kinetic studies have also been carried out in a batch adsorber over a range of initial metal ion concentration (11.87-92.34 mg/dm(3)), agitation speed (50-200 rpm) and adsorbent particle size (0.90-1.60 mm). The rate models evaluated included the pseudo-first order equation, the pseudo-second order equation and the Elovich equation, The results obtained showed that the pseudo-second order kinetic model correlated the experimental data well and better than the other models examined in this study.
