چکیده انگلیسی
Carbon-encapsulated nickel particles (Ni@C composites) for removing Fe3+ in wastewater have been prepared by the carbonization of phenolic resin mixing with nickel particles. XRD results reveal that the Ni@C composites are consisted of C, Ni, and Ni3S2. The TG-DTG curves of Ni@C composites are almost same as that of phenolic resin. The morphology investigation shows that Ni is distributed randomly on carbon. Based on analysis of N2 adsorption-desorption isotherm, the surface area and pore volume of Ni@C composites are 187.47 m2 gâ1 and 0.06900 cm3 gâ1 nmâ1, respectively. The saturation magnetization values for Ni@C composites are 68.99 emu·gâ1 determined by the Vibrating Sample Magnetometer. Ni@C composites exhibit a high adsorption capacity for Fe3+. The adsorption behavior follows the pseudo-second-order kinetic and Langmuir model between the adsorbents and Fe3+. Furthermore, the adsorption capacity of Ni@C composites derives from the attractive force between the adsorbed anion and the surface positive charge of Ni@C composites, as well as the bond between the adsorbed cation and the COOâ groups. From the above results Ni@C composites can be widely applied in wastewater treatment as a new efficiency and excellent recoverable adsorbent.
