Abstract
The composite hydrogel sodium graft poly(acrylic acid-co-N-isopropylacrylamide)/bentonite (SA-g-P(AA-co-NIPAM/BENT) emerges as an effective adsorbent to remove methylene blue (MB) and methyl violet (MV) from aqueous solutions through adsorption. Compared with the sodium graft poly(acrylic acid-co-N-isopropylacrylamide) graft copolymer SA-g-P(AA-co-NIPAM), the growth rate in terms of adsorption capacities of MV and MB is 35.5% (from 310 to 420 mg/g) and 10.2% (from 293 to 323 mg/g), respectively, with an incorporation of 0.6 g of BENT. The adsorption of MB on SA-g-P(AA-co-NIPAM/BENT) is spontaneous while MV is nonspontaneous. In addition, adsorption of both dyes satisfies the Freundlich equation and the Pseudo second-order kinetic model.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
