Fabrication of graphene oxide polymer composite particles with grafted poly amidoamine dendrimers and its application in ion chromatography

Abstract

In this work, a novel anionic adsorbent based on graphene oxide-coated polymer composite particles was synthesized by grafting with poly amidoamine dendrimers (PAMAM). The composite polymer particles (PS@GO) were prepared by coating an appropriate amount of graphene oxide (GO) sheet onto poly (styrene-divinyl benzene-glycidylmethacrylate) (PS-GMA) beads. PAMAM dendrimers were synthesized by polymerization reaction of ethylenediamine and methyl acrylate, and then grafted to PS@GO particles surface. Finally, the adsorbent was treated with 1, 4-butanediol diglycidyl ether (BDDGE) regent and characterized by various techniques. In its application, adsorption capability of the synthesized adsorbent was investigated by breakthrough curve method. According to the results, it was concluded that adsorption capabilities increased with more GO loads and higher PAMAM generations. Furthermore, this novel synthesized adsorbent was also successfully used as a stationary phase for simultaneous isocratic separation of inorganic and organic anions in ion chromatography.
