Water‐insoluble copolymer based on N‐methyl‐d‐glucamine and quaternary ammonium groups with capability to remove arsenic

Abstract: The synthesis and sorption performance of As(V) with a copolymer resin is presented. The resin was obtained via the radical polymerization of a 1:1 mixture of N‐(4‐vinyl benzyl)‐N‐methyl‐D‐glucamine and (4‐vinyl benzyl)trimethyl ammonium chloride using N,N‐methylene‐bis‐acrylamide as the crosslinker. The effect of pH, concentration, and time on the arsenic sorption was studied. The copolymer exhibited good performance over a wide pH range regardless of the initial concentrations. The equilibrium experiments pr… Show more

“…Kinetic data were treated with the pseudo‐second‐order kinetic model. The pseudo‐second‐order equation has been widely used due the excellent fit of the experimental data for the entire sorption period for many systems . The differential equation is shown in dqtdt=k2(qeqt)2 where k 2 is the pseudo‐second‐order rate constant for the sorption process (g/mg min), and q e and q t are the amounts of metal ions adsorbed per gram of polymer (mg/g) at equilibrium and time t , respectively.…”

“…The poly(HMPSA‐ co ‐SSNa) spectrum presents bands at 2926 (CC stretching), 1644 (CC), 1188 (CH, 1,4 substitution), and 1042 cm −1 (SO stretching). The poly(ClAPTA‐ co ‐SSNa) presents bands around 3430 (NH stretching), 3000 (CH stretching), and 1483 cm −1 (bending band of the quaternary ammonium groups [N + (CH 3 ) 3 ] . On the basis of these results, the structures of the copolymers are confirmed.…”

“…In addition, a copolymer resin using the monomers N ‐(4‐vinylbenzyl)‐ N ‐methyl‐ d ‐glucamine and (4‐vinylbenzyl)trimethylammonium chloride was studied to reveal the sorption of arsenic. The equilibrium experiments indicated that the copolymer achieves higher sorption capacity at pH 9.0 and that this capacity is enhanced with an increased temperature …”
