“…The detailed binding mechanism of Fe 3 O 4 modified by EDTA was described by Kataria et al [54], while the binding mechanism of investigated ions was examined by Liu et al and Xu et al [50,51]. Based on this literature, all electrochemical experiments were performed in pH 6.5 due to the formation of Cd(OH) 2 and Pb(OH) 2 /Pb (OH) 4 2À hydroxides in pH higher than 7 from Cd(II) and Pb(II) ions, respectively.…”

“…Fe 3 O 4 @SiO 2 -EDTA nanoparticles were previously obtained and they possess many advantages in comparison to EDTA. These superparamagnetic iron oxide nanoparticles have been applied as an efficient adsorbent for: methylene blue and brilliant green dyes removal from aqueous media [48], separation of rare earths [49], Cu(II), Ca(II) [50][51][52], Cd(II), Pb(II) [53,54], Ag(I), Mn(II), and Zn(II) [55] removal from an aqueous solution, and Hg(II) removal from an aqueous solution and crude petroleum samples [56].…”

This study describes the synthesis and characterization of ethylenediaminetetraacetic acid (EDTA) functionalized magnetic nanoparticles of 20 nm in size – Fe3O4@SiO2‐EDTA – which were used as a novel magnetic adsorbent for Cd(II) and Pb(II) binding in aqueous medium. These nanoparticles were obtained in two‐stage synthesis: covering by tetraethyl orthosilicate and functionalization with EDTA derivatives. Nanoparticles were characterized using TEM, FT‐IR, and XPS methods. Metal ions were detected under optimized experimental conditions using Differential Pulse Anodic Stripping Voltammetry (DPASV) and Hanging Mercury Drop Electrode (HDME) techniques. We compared the ability of Fe3O4@SiO2‐EDTA to bind cadmium and lead in concentration of 553.9 μg L−1 and 647.5 μg L−1, respectively. Obtained results show that the adsorption rate of cadmium binding was very high. The equilibrium for Fe3O4@SiO2‐EDTA‐Cd(II) was reached within 19 min while for the Fe3O4@SiO2‐EDTA‐Pb(II) was reached within 25 minutes. About 2 mg of nanoparticles was enough to bind 87.5 % Cd(II) and 54.1 % Pb(II) content. In the next step the binding capacity of Fe3O4@SiO2‐EDTA nanoparticles was determined. Only 1.265 mg of Fe3O4@SiO2‐EDTA was enough to bind 96.14 % cadmium ions while 5.080 mg of nanoparticles bound 40.83 % lead ions. This phenomenon proves that the studied nanoparticles bind Cd(II) much better than Pb(II). The cadmium ions binding capacity of Fe3O4@SiO2‐EDTA nanoparticles decreased during storage in 0.5 M KCl solution. Two days of Fe3O4@SiO2‐EDTA storage in KCl solution caused the 32 % increase in the amount of nanoparticles required to bind 60 % of cadmium while eight‐days storage caused further increase to 328 %. The performed experiment confirmed that the storage of nanoparticles in solution without any surfactants reduced their binding capacity. The best binding capacity was observed for the nanoparticles prepared directly before the electrochemical measurements.

“…The effects of dosage, pH, and initial concentration were evaluated respectively by keeping the other factors in the optimal condition. 4,8,12,16,20,24,28,32,36, and 40 mg of Fe/SA-C were mixed in 50 mL of Cd solution with the concentration of 50 mg L À1 at the designated temperature (298 K) and pH (6), respectively. The experiment with pH was controlled by adjusting the pH in the range of 3-10 with 0.1 mol L À1 NaOH and HNO 3 in 50 mL of 50 mg L À1 Cd(II) solution, and the dose of Fe/SA-C was 8 mg.…”

“…18 The loaded manganese oxide or iron oxide material proved to have an excellent removal rate and easy recyclability. [19][20][21] However, migration and surface agglomeration of metal nanoparticles might occur during loading, so it is necessary to wrap singlemetal nanoparticles with inert material to prevent the agglomeration of metal particles. 22 Carbon shell is a common coating material that not only stabilizes the internal metal particles, but also facilitates the solute diffusion, due to its mesoporous structure.…”

A novel iron-embedded carbon bead was prepared by the calcination of a calcium alginate gel bead mixed with iron nanoparticles coated by polydopamine. The prepared iron-embedded carbon bead was characterized by infrared spectrum analysis, X-ray diffraction, Raman spectroscopy, vibrating sample magnetometry, X-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy. It was discovered that the novel structure efficaciously prevented the agglomeration of iron nanoparticles. Additionally, the effects of dose, pH, exposure time, temperature and initial concentration on the adsorption of Cd(II) were studied, and the reusability of the material was analyzed. Fe/SA-C showed high Cd(II) removal capability (220.3, 225.7, 240.8 mg g À1 at 288, 298, 308 K), easy recoverability and high stability. In addition, some slightly different interpretations of the adsorption mechanism are given. This study clearly revealed that Fe/SA-C has potential application in the removal of Cd(II).

In this work, two major sources of pollution: (1) Water pollution due to heavy metals, and (2) Electromagnetic wave (EMW) pollution, often regarded as the fourth category of pollution (after air, water, and soil pollution) are addressed. A unique bio‐based triphasic nanocomposite (Fe3O4/α‐Fe2O3/carbon) is synthesized and its superior properties are demonstrated to address both types of environmental pollution. The nanocomposite, derived from lightweight apple tree roots, is used for Pb (II) ion removal from aqueous solutions via adsorption and magnetic separation. The biomass‐derived highly porous biochar decorated with iron‐oxide showed adsorption efficiency of nearly 100% and corresponding capacity of 149 mg.g−1 under optimal conditions for initial Pb (II) concentration of 50 mg.L−1. Furthermore, a remarkable adsorption capacity of 731 mg.g−1 is achieved using lower amount of the adsorbent for a slightly lower efficiency (97%). In addition, the mesoporous composite showed excellent EMW absorption efficiency with effective absorption bandwidth of 7.8 GHz and reflection loss of −61.7 dB, arising from very good impedance matching, and high dielectric and magnetic losses. This work establishes the multifunctional properties of the synthesized composite, and addresses the UN Sustainable Development Goal (SDG) 6 (Clean water and sanitation) and SDG 13 (Climate action, including pollution management).
