“…20 -26 However, little was reported on the dependence of metal ion adsorption on chelating-functional group density, pH value, and temperature and the cyclic adsorption-desorption process for their reuse. 25,28,29 In many studies, reactive monomers such as AA, 17 GMA, [21][22][23] and styrene 20,24 were copolymerized with hydrophobic monomers in the presence of a bifunctional crosslinker to prepare water-insoluble membranes and beads, and then the chelate-forming functional groups were introduced to the resultant membranes and beads. On the other hand, we aimed at preparing the practically reusable chelating membranes from the generally used polymers.…”

ABSTRACT:The chelating membranes for adsorption of metal ions were prepared by the photografting of glycidyl methacrylate (GMA) onto a polyethylene (PE) film and the subsequent modification of the resultant GMA-grafted PE (PE-g-PGMA) films with disodium iminodiacetate in an aqueous solution of 55% DMSO at 80°C. The adsorption and desorption properties of the iminodiacetate (IDA) groupappended PE-g-PGMA (IDA-(PE-g-PGMA)) films to Cu ions were almost the same in each cyclic process of adsorption in a CuCl 2 buffer at pH 5.0 and desorption in an aqueous 1.0M HCl solution. These results indicate that the IDA-(PE-g-PGMA) films can be applied to a repeatedly generative chelating membrane for adsorption and desorption of metal ions.

ABSTRACT:The chelating membranes for adsorption of metal ions were prepared by the bonding of linear and branched polyethylenimines (LPEI and BPEI) on the glycidyl methacrylate (GMA) photografted porous polyethylene (pPE) (pPE-g-PGMA) films. The adsorption and desorption properties of LPEI and BPEI-bonded pPE-g-PGMA (LPEI-(pPE-g-PGMA) and (BPEI-(pPE-g-PGMA)) films to Cu 2þ ions were investigated as a function of the grafted amount, amount of bonded PEI, molecular mass of PEI, pH value, and temperature. The amounts of LPEI and BPEI bonded to the pPE-g-PGMA films increased over the reaction time, and the bonding of LPEI and BPEI offered the water-absorptivity to the pPE-g-PGMA films. The amount of adsorbed Cu 2þ ions at pH 5.0 had the maximum value at the grafted amount of 10 mmol/g for the (LDPEI-(pPE-g-PGMA) and (BPEI-(pPE-g-PGMA) films with a constant amount of bonded PEI. The amount of adsorbed Cu 2þ ions for the LPEI-(pPE-g-PGMA) films was higher than that for the BPEI-(pPE-g-PGMA) films. The amount of Cu 2þ ions desorbed from the LPEI-(pPE-g-PGMA) and BPEI-(pPE-g-PGMA) films increased with an increase in the HCl concentration. The quantities of Cu 2þ ions of about 100% were desorbed in the aqueous HCl solutions of more than 0.1M for the LPEI-(pPE-g-PGMA) films and more than 0.05M for the BPEI-(pPE-g-PGMA) films. The amounts of adsorbed Cu 2þ ions were almost the same in each adsorption process at pH 5.0. This indicates that the LPEI-(pPE-g-PGMA) and BPEI-(pPE-g-PGMA) films can be applied to a repeatedly generative chelating membrane for adsorption and desorption of metal ions.

“…Preconcentration by separation of dissolved trace element ions onto a chemically modified solid support has been studied intensively in recent years [1][2][3][4][5][6][7][8][9][10][11][12][13] . Cellulose is a particularly attractive solid support because of its mechanical and chemical stability and its availability in pure and diverse physical forms.…”

“…These covalently bonded ligands are resistant to removal from the surface by organic solvents or water 3 . The principal success of this solid modified support with organofunctional groups is the immobilization of the desired reactive atomic group, which renders this surface highly versatile in developing various functions 13 . Thus, functional groups containing nitrogen 1,2 , sulfur 9 , oxygen 3,4 and phosphorus 6 arranged in cellulose chains render the surface useful for a variety of academic and industrial applications.…”

“…Thus, functional groups containing nitrogen 1,2 , sulfur 9 , oxygen 3,4 and phosphorus 6 arranged in cellulose chains render the surface useful for a variety of academic and industrial applications. Moreover, the majority of these anchored molecules contain nitrogen or oxygen or a combination of the two, which can bind metal ions in mono-or polydentate fashion [1][2][3][4]7,10,12,13 . Some of these modified cellulose surfaces facilitate the extraction of metal ions from aqueous and non-aqueous mediums 2,3,6,7,10 .…”

Synthesis, characterization and determination of the metal ions adsorption capacity of cellulose modified with p-aminobenzoic groups

et al. 2004

View full text Add to dashboard Cite

This paper describes the synthesis and characterization of p-aminobenzoic modified cellulose (Cell-PAB), as well as the separation and preconcentration of Cd(II), Cu(II), Ni(II), Pb(II) and Zn(II) ions from an aqueous medium using a Cell-PAB bath and the column technique. The quantity of p-aminobenzoic groups attached to the cellulose surface, i.e., 1.81±0.04 mmol/g, was determined by elemental analysis. The FT-IR spectra of Cell-PAB revealed characteristic bands of paminobenzoic groups, indicating the desired functionalization of the cellulose surface. The adsorptive capacities for the metals (Ns) Cd, Cu, Ni, Pb and Zn (Ns) were, respectively, 1.72 ± 0.02, 1.96 ± 0.02, 1.88 ± 0.04, 2.01 ± 0.03 and 1.93 ± 0.03 mmol/g. Metal separations performed in flow experiments using a column packed with 1 g of Cell-PAB and 5 mL of 1.5 mol/L HCl solution as eluent achieved an almost 100% metal ions recovery rate.
