Polyacrylic Acid-stabilized Zero-Valent Iron Nanoparticle (PAA-ZVIN) was applied to remove Lead ion (Pb2+) from aqueous solutions. In this regards, batch technique was carried out to examine the influence of experimental conditions such as pH of aqueous solutions, reaction time, concentration of PAA-ZVIN and initial concentration of Pb2+ on the removal of Pb2+ from aqueous solutions. Results of batch experiments showed that over 90% of Pb2+ removed after 15 min and at pH, 5. The removal efficiency rose with increasing PAA-ZVIN concentration. However, enhancing the initial Pb2+ concentration caused a considerable decrease in Pb2+ removal efficiency. In addition, Pseudo zero-order, Pseudo first-order and Pseudo second-order kinetic models were used to fit the experimental data of Pb2+ removal. Results of kinetic experiments indicated that Pseudo first-order kinetic model compared to other kinetic models had more ability to fit the experimental data of Pb2+ removal. In conclusion, this study revealed that PAA-ZVIN can be used as a promising adsorbent to remove Pb2+ from aqueous solutions.
