摘要：

The study was aimed to investigate the applicability of removing Pb2+ from aqueous solutions using natural walnut shell (NWS). This article presents the data for the effect of NWS dose, pH, and contact time on the adsorption of Pb2+. At optimum conditions of the above-mentioned parameters, more than 90% yield was obtained within 2 min at NWS dose of 1 g/100 mL for the initial Pb2+ concentration of 100 mg/L. Adsorption capacity was calculated from the Langmuir as 9.912 mg/g at 25 degrees C. The system was best described by the pseudo-second-order kinetic, which its equation provided evidence in favour of the adsorption kinetic.
