“…The nanoparticles loaded quercetin molecules have been reported to enhance their antioxidant capacity [6]. Different types of adsorbents, such as Chromosorb, Tenax, Porapak and Chezacarb were magnetically modified and used for the pre-concentration and isolation of the pollutant compounds [7,8].…”

“…Nowadays magnetic nanoparticles (MNPs) have found their application in the field of biomedical and material science due to their exceptional super paramagnetism properties and huge surface area [20]. Their surfaces can be functionalized and modified with different functionalities for different purposes [21][22][23][24][25][26]. Recently surface of MNPs has been modified with different groups including ionic and nonionic surfactants to extract inorganic/organic contaminants in different biological and environmental samples [27][28][29][30][31].…”

In this paper, we report a new liquid-liquid microextraction procedure called "nanoparticles decorated with a Schiff's base for the microextraction of Cd, Pb, Ni, and Co in environmental samples". The developed procedure was utilized for the extraction of Cd, Pb, Ni, and Co in environmental samples. The Schiff's base was formed by reacting salicylaldehyde with 3-aminopropyltriethoxysilane-functionalized iron oxide nanoparticles. Analyte extraction was conducted in a capillary column system loaded with modified nanoparticles and triton X-114 as dispersion medium. 1-Butyl-3-methylimidazolium hexafluorophosphate was employed as an extraction solvent. Acidified methanol in ultrasonic bath was used as desorption solvent, and elemental determination was carried out with flame atomic absorption spectrometer. Characterization of modified nanoparticles was performed with FTIR spectroscopy and transmission electron microscopy. Solution pH, nanoparticles amount, dispersant concentration, ionic liquid, and temperature were optimized for the extraction. Detection limits obtained for Cd, Pb, Ni, and Co were 0.183, 0.201, 0.241, and 0.192 μg L(-1), respectively, and enhancement factors were 79.1, 86.4, 95.7, and 82.0, respectively. The reproducibility of the developed procedure was in the range of 3.98-5.10%. Validation was checked by applying the developed procedure on certified reference water samples. The microextraction based on nanoparticles decorated with Schiff's base was successfully applied for the extraction of Cd, Pb, Ni, and Co in real environmental water samples.

“…Magnetic nanoparticles (MNPs) have potential application for material science and biomedicine because of their unique superparamagnetism and large surface area. MNPs can be functionalized by modifying their surfaces with various materials to achieve the special purposes [1][2][3][4]. Coated shellcore MNPs with carbon, alumina, and surfactants have been recently used to preconcentrate inorganic/organic contaminants in environmental and biological samples [5][6][7][8].…”

1,3-Dialkylimidazolium-based ionic liquids were chemically synthesized and bonded on the surface of magnetic nanoparticles (MNPs) with easy one-step reaction. The obtained six kinds of ionic liquid modified MNPs were characterized with transmission electron microscopy, thermogravimetric analysis, magnetization, and FTIR, which owned the high adsorption capacity due to the nanometer size and high-density modification with ionic liquids. Functionality of MNPs with ionic liquids greatly influenced the solubility of the MNPs with organic solvents depending on the alkyl chain length and the anions of the ionic liquids. Moreover, the obtained MNPs showed the specific extraction efficiency to organic pollutant, polycyclic aromatic hydrocarbons, while superparamagnetic property of the MNPs facilitated the convenient separation of MNPs from the bulks water samples.
