Synthesis and adsorption properties of magnetic resin microbeads with amine and mercaptan as chelating groups

Abstract: Three magnetic chelating resins containing amino and mercapto groups were prepared by the suspended condensation polymerization of 2-chloroethoxymethyl thiirane with diamines. The magnetic resins were microbeads whose diameter was in the range of 10 to 45 m. The structure of the resins was characterized by XPS, IR, and elemental analysis. Their adsorption properties for Hg(II), Au(III), Pd(II), Pt(IV), Ag(I), Cu(II), Zn(II), and Pb(II) were investigated. The experimental results show the magnetic resins have h… Show more

“…1,7 The polymeric adsorbents derivatized from imidazole and thiol functional groups have been used in noble metal separation. [8][9][10] Following our work on the synthesis of new modified mesoporous sorbents, 11 in this paper, we report the synthesis of amino-thiol-functionalized mesoporous silica MCM-41, its properties and sorption behavior for 18 metal ions.…”

“…[4][5][6][7][8][9][10] These terpolymers can be used as ion exchangers, 5,11 high temperature resistance material, [12][13][14][15] semiconductors, 16,17 antioxidants, 18 optical storage data, 19 moulding materials, 3,20 etc. From the literature data, it has been noted that thiol/mercapto and amine group possessing resin used as a chelating resin [21][22][23] and biphenol containing resin exhibits thermosetting, electrical insulating property 24 and in many other electronic device application. 19 In continuation to our earlier communication, [25][26][27] in this article, synthesis and characterization of terpolymer resins prepared from biphenol, thiourea, and formaldehyde are incorporated.…”
