Heavy metal ions removal has attracted considerable attention for beneficial water usage due to their long-term environmental toxicity as well as short-term public health damage. Herein, we prepared the hyperbranched poly(amidoamine) (PAMAM)-functionalized magnetite (Fe3O4) nanoparticles (PAMAM/Fe3O4) for the removal of heavy metal ions from wastewater. The properties of PAMAM/Fe3O4 were characterized by FT-IR, FESEM, HRTEM, and N2 adsorption and desorption analysis. Their magnetic properties were studied by using a superconducting quantum interference device (SQUID) magnetometer. The adsorption capability of PAMAM/Fe3O4 was also measured as a function of metal uptake time and type of heavy metal ions. PAMAM/Fe3O4 can be removed easily from water under an external magnetic field. Therefore, hyperbranched PAMAM-functionalized Fe3O4 could be considered as a potential candidate as an efficiently separable and reusable adsorbent of heavy metal ions in wastewater treatment technology. |
