Green synthesis of manganese-doped superparamagnetic iron oxide nanoparticles for the effective removal of Pb(ii) from aqueous solutions
Abstract
<jats:title>Abstract</jats:title><jats:p>In the current study, pure and manganese-doped superparamagnetic iron oxide nanoparticles (Mn-doped SPIONPs) were successfully prepared by a green approach using a fresh aqueous extract of <jats:italic>Asparagus officinalis</jats:italic> as a reducing and stabilizing agent. Magnetic behaviors of pure and Mn-doped SPIONPs were measured at room temperature against various field strengths by a vibrating sample magnetometer (VSM). The saturation magnetization was in the range of 5.39–2.07 emu. Absorption at 340 nm in the UV-visible spectrum confirmed the presence of iron oxide nanoparticles (IONPs). The presence of plant extract as a capping agent was confirmed by Fourier transform infrared (FTIR) spectroscopy. The crystalline nature of IONPs was confirmed by X-ray diffraction. A gradual increase in size was observed with increasing concentration of Mn. The synthesized materials were applied successfully as sorbent for the effective removal of lead ions (Pb(<jats:sc>ii</jats:sc>)). Experimental results of adsorption were also analyzed by Langmuir and Freundlich isotherm equations at different temperatures. The results suggested that sorption processes were spontaneous, and the synthesized SPIONPs displayed Pb<jats:sup>II</jats:sup> removal capacity at higher loadings with <jats:italic>q</jats:italic><jats:sub>m</jats:sub> of 21.3 and 29.56 mg·g<jats:sup>−1</jats:sup> for undoped and 7% Mn-doped IOPNs, respectively, as compared to the commercial activated carbon.</jats:p>
