“…A large numbers of analytical procedures for Hg(II) preconcentration and separation, mainly based on liquid-liquid extraction (Karadjova et al 2004), coprecipitation (Leyva et al 2007), solid phase extraction (SPE) (Hosseini-Bandegharaei et al 2011), ion exchange (Horvat et al 1993), and membrane separation (Bic et al 2003), have been reported.…”

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.

“…Several authors have reported on elemental analysis of wine where aqueous or matrix matched standards could not provide unbiased results and alternative methodologies such as standard additions were required to compensate for matrix effects [30,41,65]. Thus, for instance, Kildahl and Lund [65] were forced to use standard addition due to the differences in the As and Sb sensitivity between standards and untreated and decomposed wine samples in ETAAS.…”

“…ETAAS has some attractive features since the wine matrix can be partly removed during the pyrolysis step with the aid of chemical modifiers. Among the elements of interest determined by ETAAS are Pb [39,40,42,43,53,64], Cd [39,40,43,64], As [43,65] Sb [65], Al [13], Cu [43], Cr [39], V [15] and Hg [41]. HGAAS/HGAFS techniques are employed for elements such as Pb [50,51,53,66], As [52,66,67], Bi [66], Sn [66], Se [49] and Te [66].…”

Herein, at first, a magnetite@MIL-53(Fe)-NH 2 core-shell nanocomposite was fabricated and then modified via postsynthetic modification by dithiocarbamate moieties to obtain a magnetite@MIL-53(Fe)-NH-CS 2 nano-adsorbent.The constructed material was used for extraction/separation of ultra-trace Hg (II) from seawater, river water, and fish samples, and then the enriched mercury was quantified by CVAAS instrument. Characterization of magnetite@MIL-53(Fe)-NH-CS 2 nano-adsorbent was carried out by scanning electron microscopy, X-ray diffraction analysis, CHNS analysis, FT-IR spectroscopy, and magnetometry. Optimization of the affecting variables was conducted via the design of experiment methodology. After that, adsorption isotherms and kinetic studies were carried out. The experimental data were well fitted to the Langmuir and pseudo second-order kinetic models for adsorption study and kinetic study, respectively. Accordingly, a maximum adsorption capacity and a Langmuir constant (K L ) of 250 mg g À1 and 0.102 L mg À1 were obtained, respectively. The LOD and linearity of the preconcentration method were
