“…The occurrence of the flat portion in the spectrum of PNIPAAmPIDA can be ascribed to the almost complete conversion of primary amines to IDA groups. Figure 3 illustrates the 1 H NMR spectrum of PNIPAAmPIDA in dimethyl sulfoxide-d 6 , where tetramethylsilane was used as a reference material (¤ = 0.0). A characteristic signal assignable to methylene proton (NCH 2 CO, ¤ = 3.38) of iminodiacetic acid clearly indicates the successful conversion to IDA groups.…”

A thermoresponsive polymer containing highly dense iminodiacetic acid segments was newly designed for the efficient preconcentration of trace metals in water. The polymer was synthesized by the water-soluble carbodiimidemediated condensation of poly(N-isopropylacrylamide-co-acrylic acid) with polyallylamine and the subsequent conversion of amino groups to iminodiacetic acid. Metal ions in water were collected by adding the thermoresponsive polymer, sodium nitrate, dodecyltrimethylammonium chroride, and buffer components and then heating the resulting solution to form polymer deposits. The use of 0.02% (w/v) thermoresponsive polymer allowed the nearly complete (>99.8%) collection of seven metals (Be, Co, Ni, Cu, Cd, In, and Pb) in the pH range of 6.88.3. The polymer deposits were readily collected as a condensed coagulate and dissolved with a small amount of water for the analysis by graphite furnace atomic absorption spectrometry. Because of highly efficient (100-fold) concentration, these metals at pg cm ¹3 ng cm ¹3 levels were successfully determined. The precision and accuracy were evaluated by analyzing certified reference water samples.Graphite furnace atomic absorption spectrometry (GFAAS) has extensively been used for the determination of trace metals in different water samples, because of its high sensitivity, specificity, accuracy, and versatility in the analysis. However, suitable preconcentration methods are often necessary for the accurate determination of ultra-trace amounts of metals in environmental waters. Chelating ion-exchangers, 13 reagentimmobilized sorbents, 47 and synthetic zeolite 8 have been employed for this purpose. The formation of metal chelates followed by the sorption onto polymer beads, 9,10 C18-bonded silica gels, 1113 and surfactant-coated sorbents (hemi-micelles or admicelles) 1416 were potentially useful as more efficient preconcentration methods. In these methods, however, sample solutions should be passed through sorbent-packed columns, which is often tedious and time-consuming. Furthermore, the elution of trace metals is often insufficient because of irreversible sorption.An attractive alternative may be a polymer-mediated extraction of hydrophobic metal chelates. 17,18 That is based on the thermoresponsive precipitation phenomenon of a water-soluble polymer, poly(N-isopropylacrylamide) [PNIPAAm] or poly-(methyl vinyl ether), above its lower critical solution temperature (LCST, ca. 32°C 1921 ). During the precipitation, hydrophobic substances in the aqueous solution can be solubilized and incorporated into the polymer assembly. For the application to the concentration of trace metals, the polymer-mediated extraction was conducted after converting metal ions into hydrophobic chelates with appropriate chelating agents. Since the polymer aggregates were condensed to an extremely small volume, the desired metal chelates were highly concentrated. At room temperature the polymer aggregates were redissolved with a small amount of polar solvent. The resulting solution was succ...

“…Either the adsorption of chelating ligands onto these supports or the covalent coupling of chelating moiety has been used to design polymeric chelating resins, which are versatile, durable, have good loading capacity towards metals, exhibit enhanced hydrophilicity and flexible working conditions. That is why the reaction of Amberlite XAD resin with suitable chelating agents is very popular for separation and preconcentration [66][67][68][69][70][71].…”

Synthetic resin, Amberlite XAD-4 was linked covalently with the third generation supramolecule, octa-O-methoxy resorcin [4] arene through -N=N-group to form chelating resin, which has been characterized and effectively used for the separation and preconcentration of metal ions such as Ni(II), Cu(II), Zn(II) and Cd(II). Critical parameters such as pH, flow rate, sorption capacity, breakthrough studies, distribution coefficient, preconcentration factor, concentration of eluting agents responsible for quantitative extraction of metal ions were optimized. The synthesized resin showed good binding affinity towards Ni(II), Cu(II), Zn(II) and Cd(II) under selective pH conditions. Good breakthrough capacity and fast exchange kinetics of the resin lead to effective separation of metal ions from their binary and ternary mixture by column method on the basis of pH and eluting agents. The resin could be reused for about 8 -10 cycles. The proposed method having the analytical data with the relative standard deviation (RSD) < 2% and with recoveries of analytes higher than 98%, reflects upon the reproducibility and reliability of the method which has been successfully applied in the separation and determination of Ni(II), Cu(II), Zn(II) and Cd(II) ions in synthetic, natural and ground water samples.

“…Aluminium determinations can then be performed by numerous methods, such as by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Graphite Furnace Atomic Absorption Spectrometry (GF-AAS) or Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). GF-AAS has successfully been used to determine trace aluminium levels natural waters, seawater, river, soil and water (Danielsson and Sparén 1995;Mitrović et al 1998;Salomon et al 2000;Narin et al 2004;Rezaee et al 2010). Also ICP-MS method has been used in determination of aluminium in aqueous medium (water, lake water, limed lake, seawater, spring and forest soil waters; Bérubé and Brûlé 1999;Xia et al 2005;Préndez and Carrasco 2003;Sjöstedt et al 2009;Hills et al 1999;Fairman et al 1998;Rodushkin and Ruth 1997) and ICP-OES in determination aluminium in water samples (Rezaee et al 2010) drinking water (Rossiter et al 2010) or in boreal streams (Cory et al 2009).…”

The paper presents the results of aluminium determinations in ground water samples of the Miocene aquifer from the area of the city of Poznań (Poland). The determined aluminium content amounted from <0.0001 to 752.7 μg L −1 . The aluminium determinations were performed using three analytical techniques: graphite furnace atomic absorption spectrometry (GF-AAS), inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS). The results of aluminium determinations in groundwater samples for particular analytical techniques were compared. The results were used to identify the ascent Using the Mineql+ program, the modelling of the occurrence of aluminium and the following aluminium complexes: hydroxy, with fluorides and sulphates was performed. The paper presents the results of aluminium determinations in ground water using different analytical techniques as well as the chemical modelling in the Mineql+ program, which was performed for the first time and which enabled the identification of aluminium complexes in the investigated samples. The study confirms the occurrence of aluminium hydroxy complexes and aluminium fluoride complexes in the analysed groundwater samples. Despite the dominance of sulphates and organic matter in the sample, major participation of the complexes with these ligands was not stated based on the modelling.
