• Resumen

  • The method of synthesis and the arsenie removal properties of ion-exehange resins based on N-methyl-D-glueamine and trimethylammonium groups are presented. The N-methyl-D-glueamine based monomer was synthesized by the reaetion of 4-vinyl benzyl ehloride with N-methyl-D-glueamine, along with theuse of N,N-methylene-bis-aerylamide as a erosslinker reagent for polymerization. In addition, poly(4-vinylbenzyl)trimethylammonium was synthesized. Arsenatesorption studies were conducted and the pH effect, kinetics, sorption capacity, and elution performance were studied. The experimental data were fitted to kineticmodels, such as the pseudo-first order and pseudo-second order models. The pseudo-second order model exhibited the best correlation with the experimental data.The Langmuir and Freundlich isotherms were fitted to the experimental data, and the Freundlich isotherm exhibited the best fit.
