Özet
The method of synthesis and the arsenic removal properties of ion-exchange resins based on N-methyl-D-glucamine and trimethylammonium groups are presented.The N-methyl-D-glucamine based monomer was synthesized by the reaction of 4-vinyl benzyl chloride with N-methyl-D-glucamine, along with the use of N,N-methylene-bis-acrylamide as a crosslinker reagent for polymerization.In addition, poly(4-vinylbenzyl)trimethylammonium was synthesized.Arsenate sorption studies were conducted and the pH effect, kinetics, sorption capacity, and elution performance were studied.The experimental data were fitted to kinetic models, 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.
