“…The LODs of the present method for all the elements are lower than the other solid phase extraction methods given in Table 7, except for the reference 2, for Ni(II), Cu(II) and Cd(II). The EFs for the metal ions with Amberlite XAD-1180-PAN resin are better 11,23,26,35 than or comparable 9,25,36 to the other chelating resins.…”

“…Generally, chelating ligands bound to copolymers by covalent bonds are much more resistant to external effects than those immobilized by simple impregnation. [8][9][10] A number of supports and chelating ligands have been widely used in the design of chelating resins for the preconcentration and separation of trace metal ions from various matrices. The most prominent among the supports used are Amberlite XAD resins, 11,12 silica gel, 13 activated carbon, 14 activated alumina, 15 sepiolite, 16 and related polymeric supports.…”

Neste estudo foi sintetizada a resina Amberlite XAD funcionalizada por 1-(2-piridilazo)-2-naftol (PAN) e a resina resultante foi usada na pré-concentração dos íons Cr(III), Mn(II), Fe(III), Ni(II), Cu(II), Cd(II) e Pb(II) presentes em baixas concentrações em diferentes amostras. Para isso, o copolímero foi nitrado, reduzido à correspondente amina, convertido ao sal diazonato com nitrito e em reação com PAN produziu a resina complexante XAD-1180-PAN. Para o método descrito, parâmetros analíticos para recuperação dos elementos traço foram avaliados tais como, pH, volume da amostra, quantidade de resina, vazão de retenção e remoção, volume e tipo de eluente. Os metais retidos na resina XAD-1180-PAN foram eluídos com HNO 3 2 mol L -1 . A influência dos íons presentes na matriz, ou seja, Na(I), K(I), Ca(II) e Mg(II), sobre a recuperação dos elementos traço também foi avaliada, quando presentes isoladamente ou em conjunto. A repetibilidade do método foi avaliada nas condições experimentais ótimas estabelecidas. Os valores de recuperação, para todos os elementos, exceto o Cr(III), foram ≥92% e os desvios padrão relativos ≤8.5%. In this study, Amberlite XAD-1180 resin functionalized by 1-(2-pyridylazo)-2-naphthol (PAN) was synthesized and the resulting resin was used for preconcentration of Cr(III), Mn(II), Fe(III), Ni(II), Cu(II), Cd(II) and Pb(II) elements present at trace levels in different matrices. For this purpose, the copolymer was nitrated, reduced to the corresponding amine, converted to the diazonium salt with nitrite and reacted with PAN to produce the XAD-1180-PAN chelating resin. For the described method, the effect of some analytical parameters, such as pH, sample volume, resin amount, flow rates of uptake and stripping, volume and type of eluent, on the recovery of the trace elements was investigated. The metals retained on the XAD-1180-PAN resin were eluted by 2 mol L -1 HNO 3 . The influence of matrix ions, i.e., Na(I), K(I), Ca(II) and Mg(II), on the recovery of trace elements was also examined by using the developed method when they occurred both individually and together. The repeatability of the method at the optimum conditions determined experimentally was investigated. The recovery values for all the elements, except for Cr(III), were found to be ≥92% and the relative standard deviation was ≤8.5%. The 3s/b detection limits for Cr(III), Mn(II), Fe(III), Ni(II), Cu(II), Cd(II) and Pb(II) were found to be 4.1, 0.13, 2.7, 1.2, 0.19, 0.06 and 0.13 μg L -1 , respectively. The developed method was utilized for preconcentration and determination of Mn(II), Fe(III), Ni(II), Cu(II), Cd(II) and Pb(II) in tap water, rain water, and stream water, and of Ni(II), Cd(II) and Pb(II) in a certified reference material (RM 8704 Buffalo river sediment) by flame atomic absorption spectrometry (FAAS).

“…Comparisons of the sorption capacities of Amberlite XAD-1180/TAN with those of Amberlite XAD-1180, XAD-2, XAD-4 and XAD-7 supported resins show the superiority of the present resin for sorption of the trace metal ions over thiosalicylic acid, 30 chromotropic acid, 31 pyrocatechol violet, 32 pyrocatechol, 33 o-aminophenol, 20 tiron, 34 pyrogallol, 35 quinalizarin, 36 2-(methylthio) aniline, 37 2,3-dihydroxypyridine, 38 xylenol orange, 39 o-aminobenzoic acid, 19 and TAN (impregnated). 52 Better or comparable sorption capacities for the metal ions are shown by the present resin when compared with the other chelating resins.…”

“…An alternative is to introduce a functional chelating group into the sorbent. For this purpose, three different means are available: (1) the synthesis of new sorbents containing functional groups (new sorbents); [23][24][25] (2) the chemical bonding of functional groups on existing sorbents (functionalized or immobilized sorbents); [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] and (3) the physical binding of the groups on the sorbent by impregnating the solid sorbent with a solution containing the chelating ligand (impregnated, coated or loaded sorbents). [43][44][45] Chelating resins produced by the immobilization of ligands (or functional groups) were succesfully used for solid-phase extraction, since they provide some advantages, like a high sorption capacity, high enrichment factor, and endurances towards to organic and inorganic solvents.…”

A new chelating resin was synthesized by immobilizing 1-(2-thiazolylazo)-2-naphthol through the -N=N-group on Amberlite XAD-1180. The resin was used for the preconcentration of Cd(II), Co(II), Cu(II), Mn(II), Ni(II), and Pb(II) ions and their determination by flame atomic absorption spectrometry (FAAS). The influences of some analytical parameters, such as the pH, volume of the sample, flow rates of the sample and eluent, matrix components, amount of the resin, and amount and type of the eluent on the recovery, were investigated. Those metals retained on the resin at pH 8.5 were eluted with 25 mL of 2 mol L -1 HNO3. The sorption capacity of the resin was determined, except for Pb(II). The recoveries were found to be ≥95%, and the relative standard-deviation values were ≤4.3%. The detection limits were in the range of 0.1 -3.6 μg L -1. For the accuracy of the method, the analysis of a certified reference material was performed. This method was applied to environmental water samples.
