“…Compared with batch capacities reported in the literature for 8-hydroxyquinoline immobilized on other substances this value is greater than those reported by Marshall and Mottola [23], 185 µmol Cu(II) g -1 , Nelms et al [24], 86 µmol Cu(II) g -1 , Sturgeon [25], 61 µmol Cu(II) g -1 , Daihi [10], 10.4 µmol Cu(II) g -1 , and that of our previous product, 71.5 µmol Cu(II) g -1 [21]. Compared with those of other ion-chelating substances reported recently, the breakthrough capacity of our new material is equivalent to that of tiron-functionalized Amberlite XAD-2, 215 µmol Cu(II) g -1 [26], and greater than that of chromotropic acid-modified Amberlite XAD-2, 143.8 µmol Cu(II) g -1 [27], diethylenetriamine polymer, 80 µmol Cu(II) g -1 [28], and 1-(2-pyridylazo)-2-naphthol immobilized on alumina, 23.7 Cd(II) µmol g -1 [29].…”

A modified synthetic method has been developed for immobilization of 8-hydroxyquinoline on polyacrylonitrile fiber. The synthetic conditions, e.g. reagent concentration, reaction temperature and time, were optimized. The features of the newly-modified fiber are higher exchange capacity compared with most other materials containing immobilized 8-hydroxyquinoline, better mechanic characteristics, high stability at both high and low pH, and ease of synthesis. This modified fiber can concentrate and separate trace metals from matrices with higher concentrations of alkali and alkaline earth elements. To validate the characteristics of the modified fiber, trace metals Ag, Be, Cd, Co, Cu, Mn, Ni, Pb, and Zn in the certified reference materials river water (SLRS-4) and seawater (CASS-4, NASS-5, SLEW-3) were preconcentrated before determination by inductively coupled plasma mass spectrometry. Good agreement was obtained between the data obtained by this method and the certified values.Keywords 8-Hydroxyquinoline immobilized polyacrylonitrile fiber · Trace metals · Sea water · Inductively coupled plasma mass spectrometry IntroductionInductively coupled plasma mass spectrometry (ICP-MS) is one of the most accurate, sensitive, and reliable techniques for the determination of trace metals and has been widely used for determination of trace elements in environmental samples. Its low tolerance of dissolved solids (<0.1%, w/v), however, prohibits the direct analysis of trace elements in seawater by ICP-MS, because of the problem of salt deposition on the torch, sampling interface, or ion lenses. In ICP-MS interferences fall broadly into two groups, "spectroscopic", and "non-spectroscopic" or "matrix effects". The extent of the interferences depends on many factors including extraction geometry, plasma and nebulizer system operating conditions, and, most importantly, on the nature of the analytes and matrix. To minimize interferences many approaches have been recommended, including instrument optimization, use of mixed gases and/or "dry" sample introduction, sample dilution, sample-matrix matching, and use of internal standards, etc.[1]. It should be pointed out that these interferences are usually related to the nature of the sample matrix and much can be done to minimize or even eliminate potential problems by careful sample preparation. It must be admitted that for simultaneous multi-element determination by ICP-MS in a complex matrix such as seawater separation and/or pre-concentration methods are the first choice [1,2,3].8-Hydroxyquinoline is a well-characterized chelating organic ligand. It can form covalent compounds with over 60 metal ions under controlled pH conditions, and its preference for transition and heavy metals to alkali and alkaline-earth elements is well known [4]. Trace elements are usually chelated with solution of 8-hydroxyquinoline and then extracted with organic solvent [5]. In comparison with the most commonly used solvent extraction enrichment procedures, however, column solid-phase extraction...

“…Several criteria must have these types of the compounds for a substantial stability for the selective removal of heavy metal ions: the specific and fast complexation of metal cations and the reusability of them 10–11. A large number of chelating polymers incorporating amine groups were prepared and their analytical properties were investigated 12–15…”

Adsorption of Zn(II) ions from diluted aqueous solutions by the acrylic copolymer based on ethylacrylate : acrylonitrile : divinylbenzene matrix with different crosslinking degrees and ethylenediamine and triethylenetetramine functional groups was investigated. Adsorption experiments were carried out by batch method. The effects of the pH, initial concentration of zinc, time of contact, and the crosslinking degree of the copolymers were studied. On the basis of Langmuir and Freundlich isotherms, the parameters that characterize the adsorption were determined. The maximum Zn(II) retention capacity value (500 mg g Ϫ1 ) was obtained for the acrylic copolymer with 2% crosslinking degree and ethylenediamine, as functional groups.

“…This high reactivity of the epoxide group has been exploited in various applications like ionic exchangers in metal recovery (Anirudhan and Jalajamony 2010), polymer monoliths (Wang et al 2014), enzyme immobilization agents (Karagoz et al 2010), polymer resins in metal ion separation (Yu et al 2010;Arslan 2010;Baba et al 2006;Donia et al 2006), and many more. Owing to its excellent metal ion chelation, diethylenetriamine (DETA) has been used in SPE (Zhang et al 2009a, b;Bakircioglu et al 2001Bakircioglu et al , 2003Li et al 2011;Ashgar 2008;Liu et al 2006;Khanchi et al 2013). Here, we propose the use of synthesized GMA-divinylbenzene (GMA-DVB) polymer functionalized by DETA as a column packing material for detailed nickel ion preconcentration/separation studies in real environmental water samples and its subsequent determination by FAAS.…”

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.
