“…Since the certified values of Ti, V, Ga, Mo, W and Bi are still not available in the river certified reference materials, the values obtained by this work are compared with the literature values (see Tables 3 and 4). [15][16][17] The analytical data obtained by the proposed method are in good agreement with the literature values.…”

Adsorption Behavior of Metal Ions on Cross-linked Chitosan and the Determination of Oxoanions after Pretreatment with a Chitosan Column

et al. 2000

Chitosan, an N-deacetylation product of chitin, is one of the useful chelating polymers, and is capable of adsorbing a number of metal ions. Muzzarelli et al. have reported that chitosan without cross-linking can adsorb transition-metal ions from aqueous solutions at neutral pH, 1,2 and other researchers have reported that chitosan can adsorb Hg(II), Cu(II), Cr(III), Pb(II), UO2 + and Cd(II). [3][4][5][6][7][8] However, the adsorption behavior of metal ions has not yet been investigated in detail, though chitosan seems to possess a promising ability of metal collection.Non-cross-linked chitosan can be easily soluble in some acidic media. Such a characteristic is one of the serious disadvantages from a practical viewpoint of metal collection and concentration. Therefore, several types of chemically cross-linked chitosan have been prepared and their metal adsorption properties have been examined. Cross-linking can make chitosan hardly soluble in acidic media. Ohga et al. reported that cross-linked chitosan, which was prepared by cross-linking with (chloromethyl)oxyrane after complexation of chitosan with metal ions, can act as effective adsorbents for Cu(II) and Hg(II), 9 and Inoue et al. reported the adsorption behavior of 15 elements on cross-linked chitosan by a batchwise method.10,11 Koyama et al. and Kurita et al. also synthesized a cross-linked chitosan with glutaraldehyde, and examined the adsorption behavior of Cu. 12,13 Further, Rorrer et al. examined adsorption isotherms of Cd(II) on porous chitosan beads crosslinked with glutaraldehyde at 25˚C and pH 6.5 over the concentration range 1 -1690 mg l -1 .14 Such studies mainly examined the adsorption behavior of several metal ions at ppm levels on a cross-linked chitosan by batchwise equilibration techniques, and did not aim to collect and concentrate trace amounts of metal ions at ppb and subppbs (1 ppb = 1 ng ml -1 ). Further, few papers have reported so far about the desorption and recovery of metal ions adsorbed on cross-linked and non-cross-linked chitosan.In this work, the authors examined in detail, for the first time, the adsorption behavior of a number of elements (60 elements) at the 10 ng ml -1 level by a column pretreatment method using commercially available high-porous cross-linked chitosan beads (CHITOPEARL AL-01) (Fuji Spinning Co., Ltd. Tokyo, Japan), and found the useful ability of the cross-linked chitosan as a packing material for collecting and concentrating trace amounts of metal ions in river-water samples. Furthermore, the determination of six oxoanions in river-water samples (reference materials distributed by the Japan Society for Analytical Chemistry: JAC 0031 and JAC 0032) was carried out using air-segmented flow injection/ICP-MS (AFI/ICP-MS) after preconcentration with a chitosan column. The analytical results obtained for the determination of oxoanions agreed well with other literature values.

“…The thus-obtained analytical results by the present methods, as well as the certified values, are summarized in Table 6 for JAC 0031 and in Table 7 for JAC 0032. The analytical results obtained by other workers are also listed in both Tables 6 and 7 for a comparison of the present data with reference values obtained by other methods, such as ICP-MS 27,37 and INAA. 38 In an analysis of JAC 0031 by SFI/ICP-MS without any column pretreatment procedures, the results for B, Al, Cr, Mn, Cu and Zn agreed well with the certified values, whereas the results for Fe, Ni, Co and As deviated positively from the certified and/or reference values.…”

“…Therefore, most of recent studies with Chelex-100 have been carried out by a batch method without a column. [27][28][29][30][31] Though an 8-hydroxyquinoline (8HQ) type chelating resin chemically bonded to silicagel does not exhibit swelling with a pH change, the stability constant of 8HQ-Ca and 8HQ-Mg complexes are relatively close to those of some 8HQ-transition metal complexes. Therefore, most of the calcium and magnesium are recovered with transition metals, which can cause severe spectral interference with the determination of trace elements in sample solutions.…”

Simultaneous Determination of Trace Elements in River-water Samples by ICP-MS in Combination with a Discrete Microsampling Technique after Enrichment with a Chitosan-based Chelating Resin

et al. 2000

View full text Add to dashboard Cite

A new technique for the preconcentration of trace elements and matrix elimination with a chitosan-based chelating resin was proposed as a useful pretreatment prior to a measurement by inductively coupled plasma-mass spectrometry (ICP-MS). A small volume of the sample solution (80 µl) was discretely introduced into a nebulizer of ICP-MS using a segmented flow injection (SFI) system; a maximum of fifteen elements were simultaneously measured by a single injection. A chitosan-based chelating resin containing iminodiacetate (IDA) functional groups was used for matrix elimination and enrichment of analyte metal ions. Several metal ions, such as Al, Fe, Ni, Co, Cu, Zn, Ag, Cd, Pb and U, were quantitatively retained on the IDA chelating resin in a micro-column (resin: 1 ml) at pH 6, whereas Na, K, Mg and Ca were completely eluted from the column by washing with an ammonium acetate solution. The concentrations of 24 and 26 elements in river water certified reference materials, JAC 0031 and JAC 0032, respectively, were determined by the proposed SFI/ICP-MS system after pretreating the samples with the proposed technique, as well as without any pretreatment. The thus-obtained analytical data were evaluated by comparing them with the reference values, as well as with those obtained in other studies.
