“…Despite the selectivity and sensitivity of modern analytical techniques, there is a crucial need for the preconcentration of trace elements before their analysis. Consequently, several different types of methods, such as chemical precipitation [1,2], solvent extraction [3], nanofiltration [4], and adsorption [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], have been used for the removal of heavy metal ions.…”

“…Up to now, a variety of adsorbents have been reported as materials for the adsorption of heavy metals including activated carbon [5,6], modified silica gel [7,8], multiwalled carbon nanotubes (MWCNTs) [9,10], biomaterials [11], ion-imprinted materials [12,13], polymers [14][15][16][17][18], inorganic materials [19], and sorption resins [20][21][22]. For example, thiourea-modified magnetic chitosan microspheres (TMCS) have been prepared by Zhou et al [11].…”

“…The determination of heavy metals at trace level in various samples has received special attention of researchers as a way to assess the early impact on humans and the environment (Islam et al 2010(Islam et al , 2012a(Islam et al , 2014. This determination by sophisticated analytical techniques like inductively coupled plasma (ICP)-MS, ICP-AES, ETAAS, and GFAAS is limited due to matrix interference.…”

In this study, mesoporous glycidyl methacrylate-divinylbenzene-based chelating resin was synthesized and grafted with diethylenetriamine through epoxy ring-opening reaction. The synthesized resin was characterized by elemental analysis, infrared spectroscopy, surface area and pore size analysis, scanning electron microscopy, energy-dispersive spectroscopy, and thermogravimetry. The resin was used for the first time as an effective sorbent for the preconcentration of nickel in electroplating wastewater samples. The analytical variables like pH, flow rate for sorption/desorption, and eluate selection were systematically investigated and optimized. The uniform and monolayer sorption behavior of resin for nickel was proved by an evident fit of the equilibrium data to a Langmuir isotherm model. Under optimized conditions, the resin was observed to show a good sorption capacity of 20.25 mg g(-1) and >96% recovery of nickel even in the presence of a large number of competitive matrix ions. Its ability to extract trace amount of nickel was exhibited by low preconcentration limit (5.9 μg L(-1)). The calibration curve was found to be linear (R(2) = 0.998) in the concentration range of 6.0-400.0 μg L(-1). Coefficient of variation of less than 5 for all the analysis indicated good reproducibility. The reliability was evaluated by the analysis of standard reference material (SRM) and recovery experiments. The applicability of the resin for the systematic preconcentration of nickel is substantiated by the analysis of electroplating wastewater and river water samples. Graphical abstract ᅟ.

“…Therefore, it can be said that a well-chosen adsorbent determines the efficiency of the SPE technique. Amberlite 2 Journal of Chemistry XAD5 resins which are able to adsorb metal complexes have received a great deal of attention because of versatile usage with or without derivatization [19][20][21][22]. In particular, Amberlite XAD-7 resin possessing an intermediate polarity and hydrophilic surface as a highly crosslinked macroreticular acrylic resin (polyacrylic acid ester polymer) has been performed in SPE studies [23][24][25].…”

A new procedure for separation and preconcentration of trace amounts of Cu(II), Ni(II), Fe(III), Zn(II), Cr(III), Cd(II), and Pb(II) in fish samples was proposed. The procedure is based on the adsorption of these metal ions on the column of Amberlite XAD-7 as congo red complexes prior to their determination by flame atomic absorption spectrometry (FAAS). Several factors that can affect the sorption and elution efficiency of the metal ions were investigated and optimized. The sorption was quantitative in the pH range of 6.0-9.0 for Cu(II) and Ni(II), 5.5-8.0 for Fe(III), 6.0-8.5 for Zn(II) and Cd(II), and 7.0-8.5 for Cr(III) and Pb(II). The optimum pH for simultaneous retention was 7.5. The sorption capacity of the resin was found to be 0.89, 0.72, 0.82, 0.61, 0.53, 0.84, and 0.78 mg/g for Cu(II), Ni(II), Fe(III), Zn(II), Cr(III), Cd(II), and Pb(II), respectively. The precision of the method was evaluated as the relative standard deviation obtained by analyzing a series of six replicates and below 6% for all seven elements. The validation of the method was performed by the analysis of certified reference materials. The proposed method was successfully applied to separation/ preconcentration and determination of these metals in fish samples.
