Solid Phase Extraction of Trace Al(III), Fe(II), Co(II), Cu(II), Cd(II) and Pb(II) Ions in Beverages on Functionalized Polymer Microspheres Prior to Flame Atomic Absorption Spectrometric Determinations

Solid-Phase Extraction for Environmental Analysis

“…7 Berber and Alpdogan synthesized 2-aminobenzothiazole functionalized polymeric microspheres were used as an SP adsorbent for the selective preconcentration of Al(III), Fe(II), Co(II), Cu(II), Cd(II), and Pb(II) in beverages by using FAAS. 8 The detection limits obtained under the optimal conditions were in the range of 0.26 -2.20 μg L -1 . Mizuguchi et al reported on a rapid enrichment method for the determination of nickel ion using a nanofiber-composite membrane filter.…”

Synthesis and characterization of 1,3‐butadiene‐containing hyperbranched conjugated polymers as a selective chemosensors for Fe3+ ions

“…Current reported metal ions detection and quantification methods include the electrochemical method, atomic absorption spectrometry, inductive coupled plasma atomic emission spectrometry, colourimetry, biosensor and nanosensors methods. [ 14–19 ] However, most of these methods require expensive instruments, and exhibit poor selectivity and low detection limit. Therefore, there is an urgent need to develop effective and rapid methods and materials for detecting iron ions, which can be applied in environmental, biological and industrial samples.…”

Thermal Decomposition Behavior of a Chelating Resin Immobilizing Carboxymethylated Polyethyleneimine: Possibility of Estimation of Carboxymethylation Rate

“…Solid-phase extraction is widely utilized for separation and preconcentration of trace elements; [1][2][3][4] various solid-phase extraction materials, including chelating resin, are proposed even now. [1][2][3][4][5][6][7] A chelating resin immobilizing carboxymethylated polyethyleneimine (CM-PEI), which is commercially available as Presep PolyChelate (FUJIFILM Wako Pure Chemical), has an excellent ability for solid-phase extraction of trace elements. [8][9][10][11][12][13][14][15] This resin is prepared by immobilizing PEI on a porous methacrylate resin (copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate) and then carboxymethylating amino groups in the PEI using sodium monochloroacetate.…”
