Abstract:
In the present work, thiosemicarbazide modified chitosan nanoparticles structure (TCS NPs) have been successfully synthesized for the removal of highly toxic Pb2+ ions and its properties were characterized. Prepared nanocomposite properties were characterized by Fourier transform infrared (FTIR) spectroscopy. The results showed that the TCS nanoparticles were successfully synthesized. The Pb2+ removal by the TCS adsorbent was investigated using batch adsorption technique and The effect of pH on Pb2+ removal was considered in the pH range of 2-5 at the contact time of 3 h, adsorbent amount 22 mg and all stages were performed at room temperature. Adsorption of Pb2+ ions on the surface of the adsorbent depends on the pH of the solution. In this study, pH 5.2 was chosen as an optimum pH for Pb2+ ions rejection.
