“…The recoveries for these elements were very satisfactory. In addition, PAN-MCM-48 showed high tolerance to interferences from the matrix ions, and finally, the important features of the proposed method were its high adsorption capacity, good preconcentration factor, and low detection limit which is distinctive among other solid-phase extraction methods (Nabid et al 2014;Behbahani et al 2013cBehbahani et al , 2014d. The proposed method was applicable to the determination of trace amount of these heavy metals in real water and food samples.…”

“…However, the level of heavy metal concentration in environmental samples is fairly low and preconcentration procedures are often required (Duran et al 2009). Among numbers of methods such as liquid-liquid extraction (Komjarova and Blust 2006;Wei et al 2003;Behbahani et al 2014c), chemical precipitation (Matlock et al 2002a(Matlock et al , 2002b, ion exchange (Akcin et al 2011), reverse osmosis adsorption (Akieh et al 2008), and solid-phase extraction (SPE), solid-phase extraction has attracted a c o n s i d e r a b l e a m o u n t o f i n t e r e s t s f o r t h e preconcentration of toxic heavy metals (Tuzen et al 2008;Behbahani et al 2014dGhaedi et al 2008Ghaedi et al , 2007, due to higher efficiency and low consumption of pure organic solvents. This method is simple, efficient, selective, cost-effective, and it is easy to automate without need for emulsion, and it is also safe, regarding to the reagents that has employed (Nabid et al 2014).…”

Solid-phase extraction is one the most useful and efficient techniques for sample preparation, purification, cleanup, preconcentration, and determination of heavy metals at trace levels. In this paper, functionalized MCM-48 nanoporous silica with 1-(2-pyridylazo)-2-naphthol was applied for trace determination of copper, lead, cadmium, and nickel in water and seafood samples. The experimental conditions such as pH, sample and eluent flow rate, type, concentration and volume of the eluent, breakthrough volume, and effect of coexisting ions were optimized for efficient solid-phase extraction of trace heavy metals in different water and seafood samples. The content of solutions containing the mentioned heavy metals was determined by flame atomic absorption spectrometry (FAAS), and the limits of detection were 0.3, 0.4, 0.6, and 0.9 ng mL(-1) for cadmium, copper, nickel, and lead, respectively. Recoveries and precisions were >98.0 and <4%, respectively. The adsorption capacity of the modified nanoporous silica was 178 mg g(-1) for cadmium, 110 mg g(-1) for copper, 98 mg g(-1) for nickel, and 210 mg g(-1) for lead, respectively. The functionalized MCM-48 nanoporous silica with 1-(2-pyridylazo)-2-naphthol was characterized by thermogravimetry analysis (TGA), differential thermal analysis (DTA), transmission electron microscopy (TEM), Fourier transform infrared spectrometry (FT-IR), X-ray diffraction (XRD), elemental analysis (CHN), and N2 adsorption surface area measurement.

“…[22][23][24] It is simple, fast, and does not require large amounts of organic solvents. 25,26 Up to now, the original In situ IL-DLLME is based on the formation of a waterimmiscible IL using a metathesis reaction between a watermiscible IL and anion exchange salt into sample solution. As a consequence, the hydrophilic IL is transformed to a hydrophobic IL which can act as an extraction phase.…”

A procedure has been developed for simultaneous separation/preconcentration of copper, nickel, and zinc based on in situ ionic liquid-based dispersive liquid-liquid microextraction method as a prior step to their determination by flame atomic absorption spectrometry. The analytes reacted with sodium diethyl dithiocarbamate at pH 7 to form hydrophobic chelates, which were separated and preconcentrated in the ionic liquid phase. The method is fast, simple, accurate, and environmentally friendly. The parameters affecting the extraction efficiency of the proposed method such as the pH of sample solution, centrifugation time, type and volume of the dispersive solvent, and the salt effect were studied. Enrichment factors of 61.8, 61.2, and 40.0 and detection limits of 0.79, 0.93, and 0.71 µg L -1 were obtained for copper, nickel, and zinc, respectively. The relative standard deviations based on six replicate measurements were between 1.0 and 2.7%. The method was successfully applied to the extraction and determination of these metals in wastewater and alloy samples.Keywords: dispersive liquid-liquid microextraction, nickel, zinc, copper, ionic liquid, sodium diethyl dithiocarbamate IntroductionIn the priority list of Agency for Toxic Substances and Disease Registry (ATSDR), Ni is at rank 57, Zn at 75, and Cu at 118.1 Nickel is essential for many biological activities such as activation of some enzymes and enhancement of insulin activity. 2 Copper plays important roles in metabolism, including antioxidant effects, energy generation and incorporation of Fe into hemoglobin.3 Zinc also has an important role in various biological systems, such as gene expression, protein-protein interaction, and neurotransmission. 4 Although nickel, copper, and zinc come into the category of essential trace elements, when they are taken at high levels, they can also produce toxic effects. 5-8Thus, determination and monitoring of these toxic metals in industrial effluent, biological samples and food stuff are of prime concern.The trace elements level in samples to be analyzed are sometimes lower than the detection limit of analytical instruments such as flame atomic absorption spectroscopy (FAAS), inductively coupled plasma optical emission spectrometry (ICP OES) and graphite furnace-atomic absorption spectrometry (GF-AAS).9,10 Therefore, a suitable sample pretreatment step is a required step prior to the analysis. Several techniques including solid phase extraction, 11,12 liquid-liquid extraction, [13][14][15][16] cloud point extraction, 17-19 and co-precipitation 20,21 have been employed to solve this issue. Most of these techniques suffer from limitations that limit their application. Some examples of these limitations include significant chemical additives, solvent losses, large secondary wastes, unsatisfactory enrichment factors, complex equipment, and high time consumption.Dispersive liquid-liquid microextraction (DLLME) overcomes some of the drawbacks of old sample preparation techniques. [22][23][24] It is simple, fast, and does n...
