“…FTIR of L-Ser capped powder dispersed in dimethyl sulfoxide are depicted in Figure 5 and clearly have the spherical morphology with average particle size of 5.9 nm and standard deviation 1.58 nm of L-Ser capped Fe 3 O 4 NPs. A selected area electron diffraction pattern obtained from the particles is given in Figure 5(c) and in good agreement with the characteristic electron diffraction pattern of Fe 3 O 4 NPs of spinel structure [26]. …”

This paper describes a green one-pot synthesis of L-Serine (L-Ser) capped magnetite nanoparticles (Fe 3 O 4 NPs) and its potential application for adsorption of RhB dye from aqueous solution. The surface property, structure, morphology and magnetic properties of as prepared L-Ser capped Fe 3 O 4 NPs were characterised through UV-Visible spectroscopy, Fourier transform-infrared spectroscopy, X-Ray Diffraction (XRD), scanning electron microscope, transmission electron microscope (TEM) and vibrating sample magnetometer (VSM). The XRD results were indicated the formation of high crystalline spinel type Fe 3 O 4 NPs. TEM images were shown the spherical shape of L-Ser capped Fe 3 O 4 NPs with particle size of 5.9 nm. The VSM curve showed the superparamagnetic behaviour of L-Ser capped Fe 3 O 4 . A plausible interaction mechanism of L-Ser and Fe 3 O 4 NPs was also investigated. L-Ser capped Fe 3 O 4 NPs due to its large surface area and a strong magnetism was shown potential adsorption efficiency towards RhB dye from aqueous solution. The adsorption isotherm data fitted well with Langmuir isotherm model and the monolayer adsorption capacity (q e,exp ) was found to be 6.82 mg/g at pH 7.4 and 300 K. The experimental kinetic data fitted very well with the pseudo-second-order model. The thermodynamic studies reveal that adsorption efficiency is critically dependent on temperature.

“…Fig. 1 , respectively [12,13]. The peaks at 3,465 and 3,139 cm -1 are ascribed to N-H stretching vibrations of amino groups in the structural units of the PANi, while the peaks at 1,560 and 1,500 cm -1 are due to the C=C stretching vibration of quinoid rings and benzenoid ring units respectively [13].…”

Recently nano-sized conducting polymers have gained ample attention because of their unique properties and promising potentiality in nanomaterials and nanodevices. Among the conducting polymers, polyaniline (PANi) is the most studied conducting polymers because of its low monomer cost, ease of preparation, high conductivity in doped form, excellent environmental stability, controllable physical and electrochemical properties by oxidation and protonation. In this investigation magnetic PANi composite particles were prepared following a novel approach by using citric acid for the first time as dopant, surfactant and solubilizing agent. As synthesized citric acid doped

“…Among those, nanocomposite of MNPs with polyaniline (emeraldine base coating) has been extensively studied in syntheses and applications for medical and environment purposes. Compared to many coating polymers, polyaniline (PAni) is highly compatible in bio-and environment applications due to its good environment stability, low monomer cost, ease of syntheses and purification, and convenient degrading process [23,24]. The PAni/MNP nanocomposite can also be mixed with other polymer substrates such as poly(p-hydroxyaniline) and polyacrylonitrile to increase hydrophilicity of materials in aqueous media and mechanical strength of materials in product processing [24,25].…”

Nevertheless, it is noticeably remarked that there has been no study informing PAni-coated MNPs to be an As(III) adsorbent as well as performing recyclability of this material in metal ion adsorption.…”

In this study, nanocomposites composed of magnetite nanoparticles (MNPs) coated with polyaniline fabricated by in situ polymerization were prepared for arsenic adsorption. Properties of particular MNPs and their nanocomposites were characterized with scanning electron microscopy, X-ray diffraction spectroscopy, and Fourier transform infrared spectroscopy. The As(III) concentration before and after adsorption on nanocomposites was detected by atomic absorption spectroscopy method and then compared with the results measured by a self-developed potentiostat system with anodic stripping voltammetry method. The polyaniline coating resulted in an improvement for As(III) adsorption ability of magnetite nanoparticles, and among the three compositions of PAni/MNP nanocomposites, the 5 wt% PAni showed the highest capability of As(III) adsorption (or removal) of 50 mg/g. Performing pH investigation, the concentration of remaining As decreased when pH increased from 2 to 5 and reached saturation value at higher pH. Above all, the electronic device can be integrated with As(III) removal system using PAni/MNP nanocomposites, proving to act as an independent monitoring system, and even more the adsorbent on the composites could be removed and the recyclability of the material was also investigated.
