This work describes a novel Fe3O4@SiO2@polythiophene magnetic nanocomposite and its application in the preconcentration of Hg(II) ions. The parameters affecting the preconcentration procedure were opted by a Box-Behnken design through response surface methodology. Three factors (uptake time, magnetic nanosorbent amount, and pH of sample) were selected as the main factors affecting the sorption step, while four variables (type, volume and concentration of the eluent as well as the elution time) were selected as main factors in the optimization study of the elution step. Following the sorption and elution of Hg(II), it was quantified by cold vapor atomic absorption spectrometry. Under the optimum condition, the limit of detection was 0.02 ng mL(-1) and all the relative standard deviations were less than 9.2 %. The obtained sorption capacity of this new sorbent was 59 mg g(-1). Finally, this nanocomposite was successfully applied to the rapid extraction of trace quantities of Hg(II) ions in sea food samples and satisfactory results were obtained.

“…One group of the modifier compounds, which have been widely used recently, are conducting polymers (CPs) [16,17]. Among the different CPs used as SPE sorbent, the great attentions have been focused on polythiophene (PT), which is more stable than the other CPs in high temperature, air, moisture and various solvents [18][19][20]. Yamini et al [19,20] used PT-coated Fe 3 O 4 as a MSPE sorbent.…”

“…Such MPCs find potential applications in electrochemical devices, electromagnetic interference, nonlinear optics, microwave-absorbing materials, electromagnetic shielding, molecular electronics, catalysis, separation, etc. Fe 3 O 4 nanoparticles have been coated with conductive polymers like polypyrrole [12], polythiophene [13] and polyaniline [14]. Among them, polyfuran (PFu) is known as a conjugated heterocyclic polymer which can be used as a humidity sensor, and acts as an optoelectronic device since its color changes from yellow-brown to black-brown upon doping [15].…”

We describe magnetite nanoparticles modified with polyfuran (PFu/Fe 3 O 4 ) and their use as adsorbents for the solid-phase extraction of the polycyclic aromatic hydrocarbons (PAHs) naphthalene, fluorene and anthracene from water and urine samples. The PFu/Fe 3 O 4 nanocomposite was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and vibrating sample magnetometry (VSM). The adsorbent was magnetically separated from the sample, extracted with dichloromethane, and the extracts were submitted to gas chromatographic analysis with flame ionization detection. The amount of adsorbent, adsorption and desorption time, salt addition and desorption solvent were optimized. The method displays detection limits (at an S/N ratio of 3) in the range from 5 to 20 pg mL −1 , and the limits of quantification (at an S/N ratio of 10) are between 20 and 50 pg mL −1 . Relative standard deviations (RSDs) for intraand inter-day precision are 4.1-5.6, and 5.3-6.5 %, respectively. The feasibility of the method was demonstrated by extracting and determining PAHs in (spiked) real water and urine samples.
