A glycidyl methacrylate-based resin with pendant urea groups as a high capacity mercury specific sorbent Authors:Bıçak, Niyazi; Sherrington, David C.; Şungur, Şana Kutun; Tan, Nükhet
Publisher and Date:(Elsevier Science Bv, 2003)Polymer-supported pendant urea groups have been demonstrated to be very efficient in selective removal of mercuric ions from aqueous solutions. Methyl methacrylate (0.5 mol)-glycidyl methacrylate (0.4 mol)-divinylbenzene (0.1 mol) terpolymer beads have been prepared by suspension polymerisation. Urea functions have been incorporated into the bead polymer (210-420 mum) via a two-step modification of the epoxy groups involving firstly reaction with excess of triethylenetetramine followed by acidic ...
