Resumen

OZKULA, GULSAH et al. ARSENIC SORPTION USING MIXTURES OF ION EXCHANGE RESINS CONTAINING N-METHYL-D-GLUCAMINE AND QUATERNARY AMMONIUM GROUPS. J. Chil. Chem. Soc. [online]. 2016, vol.61, n.1, pp.2752-2756. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072016000100001.

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.

Palabras clave : Arsenie; N-methyl-D-glueamine; ion exehange; ion exehange resin mixture.
