“…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.…”
