“…It is known that high concentrations of interfering ions cause matrix effects in the spectroscopic determination of metal ions in environmental and food samples (41). The influence of foreign ions such as Cd 2+ , Cu 2+ , Ni 2+ , Zn 2+ , Co 2+ , Na + , K + , Ca 2+ , Mg 2+ , and Fe 2+ on the recovery of Pb 2+ and Al 3+ was examined under optimum experimental conditions.…”

“…One of widely used and fast emerging preconcentrative separation techniques for this purpose is the solid-phase extraction (SPE) due to its advantages (Daniel et al 2006). So far, different SP-extractors were used for determination of Cd(II) and Zn(II) from different real samples (Rajabi et al 2014;Behbahani et al 2013Behbahani et al , 2014Barciela-Alonso et al 2014;Jamshidi et al 2011;Ghaedi et al 2013a, b, d, e;Shakerian et al 2012). An efficient solid-phase extractor should consist of a stable and insoluble porous matrix having suitable active groups that interact with heavy metal ions (Fang et al 2005).…”

In this work, silica fume (SF) is used as a solidphase extractor for extraction of Zn(II) and Cd(II) from aqueous solutions. Characterization of SF is performed by Fourier transform infrared, X-ray diffraction, transmission and scanning electron microscopy. The optimum experimental conditions for the two metal ions are investigated using batch and column techniques. The maximum adsorption capacity values are found to be 54.13 and 121.28 mg g -1 at the optimum pH 6.0 and 8.0 for Zn(II) and Cd(II), respectively. The equilibrium data are analyzed using the Langmuir, Freundlich, and Temkin isotherms by nonlinear regression analysis. Also, the kinetics analysis revealed that the overall adsorption process is successfully fitted with the pseudo-second-order model. The method is applied for determination of the target metal ions in pharmaceutical and environmental samples using squarewave anodic stripping voltammetry. The limit of detection (LOD) values are 0.102 and 1.43 9 10 -3 mg L -1 for Zn(II) and Cd(II), respectively. The percentage recovery values are 98.8-100.5 % which indicate the success of the proposed method for determination of Zn(II) and Cd(II) without interfering effects.

“…In the viewpoint of simplicity, cleanness, low reagent, and organic consumption, SPE is most widely applied and is preferred to LLE [13]. Over the past few years, several adsorbents, such as activated carbon [14], silicagel [15], exfoliated graphite [16], carbon nanotubes [17], ion-imprinted polymers [18,19], modified organo-nanoclay [20,21], hydrogel [22], activated alumina [23], modified silica [24,25], and modified nanoalumina [26], have been used for the preconcentration of metal ions. Fe 3 O 4 nanoparticles (NPs) as an efficient class of adsorbent, are receiving increasing interest in recent years.…”

In this work, magnetic Fe 3 O 4 nanoparticles (NPs) were synthesized by ultrasonic chemical co-precipitation method. Then hydrophobic ionic liquid (IL), as a green coating agent, was deposited on the surface of synthesized NPs in order to improve their extraction capability toward Pd(II) ions as diethyldithiocarbamate (DDTC) complex. Scanning electron microscopy, thermogravimetric analysis, X-ray diffraction (XRD), vibrating sample magnetometer (VSM), and Fourier transformed infrared (FTIR) techniques were used for characterization of the adsorbent. The adsorption rate was fast and the equilibrium time was achieved within 4 min due to the strong interaction of Pd-DDTC complex with the IL and the absence of internal diffusion resistance. The separation of the adsorbent from aqueous bulk was achieved after about 2 min by a magnet, so no centrifugation or filtration was required. The effective parameters such as pH, concentration of ligand, amount of adsorbent, and the extraction time were inspected by using a central composite design in order to identify the most important parameters and their interactions. Under optimum conditions, the detection limit was 0.82 ng mL −1 and the relative standard deviation (n = 10) was 2.8% for 100 ng mL −1 of Pd(II). The proposed method was applied for the preconcentration of Pd(II) from road dust, liver, and water samples, and it was found that the amounts of palladium ions in dust and liver samples were 104 and 8.7 ng mL −1 , respectively.
