Selective binding of mercury ions by poly(4-vinylpyridine) hydrochloride resin

Abstract: ABSTRACT:The binding ability of poly(4-vinylpyridine) hydrochloride resin for Cu(II), Cd(II), Zn(II), Hg(II), Pb(II), Cr(III), and U(VI) was investigated. All these ions, except Hg(II), could be not removed from aqueous solutions under the same conditions. The selective sorption of Hg(II) from mixtures of ions was observed. The elution of Hg(II) bound to the resin was also investigated using various concentrations of nitric acid and perchloric acid. Due to rapid complexation, a high mercury ion-binding capacit… Show more

“…The increase in absorbance at 1640 cm À1 corresponds to protonated or acidic form of pyridine (pyridinium NH + ) [29]. The increase in absorption of NH stretching band at 3450 cm À1 further confirms the bonding of the Hg 2+ with pyridine group [30].…”

“…Mercuric ions interact strongly with ligands containing nitrogen or sulfur donor atoms, including pyridine, poly(ethylenimine), thioether, thiourea and phosphine sulfide. Recently, many of these polymers such as porous cellulose carrier modified with poly(ethyleneimine) [11], a resin incorporating imidazolylazo function in a polystyrene bed [12], poly(4-vinylpyridine) hydrochloride resin [13], polymersupported thiacrown( [14] aneS 4 and [17]aneS 5 ) [14], dithiocarbamate-incorporated monosize polystyrene [15], modified chloromethylated polystyrene-PAN [16], 6-mercaptopurinylazo resin on polystyrene-divinylbenzene [17], N-chlorosulfonamide groups into polystyrene-divinylbenzene and polyacrylamide onto functionalized polystyrenedivinylbenzene [18], grafted acrylate esters from cross-linked polystyrene beads [19], poly(2-hydroxyethyl methacrylate) gel beads modified with poly(ethyleneimine) [20], polystyrenesupported amines [21], immobilized N-methyl-D-glucamine [22] and polymeric thiacalix [4]arenas [23] were synthesized and used for the selective removal of mercury ions. In this study, we report a convenient method for the synthesis of a new resin containing pyridine-2,6-dicarboxylic acid (PDC) on chloromethylated polystyrene (CMP) for the removal of mercury(II) in environmental samples.…”

“…Poly-4-vinylpyridine (P 4 VP) [2][3][4][5], polyvinylpyrrolidone, polyacrylic acid [6,7], polyethyleneimine [8] alone or combined are used to reach very low concentrations. In general, waste management becomes more difficult and more expensive as feed concentration in the waste stream decreases and for these reasons, the reuse of the extraction materials and the minimization of secondary waste volume must become the focus of scientific efforts.…”

“…Our new strategy is to use poly-4-vinylpyridine polymers electro-grafted as thin films [16,17] for which electricity will now be used to destabilize the complex. The capture will thus be due to complexing forces, as poly-4-vinylpyridine is well known in the field of complexing resins and proved to be efficient in extracting copper ions [2,3], and release will use a simple electrical polarization instead of chemicals for the recovery step. However, using electrical power with organic films is not straightforward.…”
