|Title:||Attachment of linear poly(amido amine) to silica surface and evaluation of metal-binding behavior|
|Abstract:||The investigation reports preparation of two new adsorbent materials, SiPOLHET and SiPOLHOM, by attachment of linear poly(amido amine) (PAA) to silica surface by adopting heterogeneous and homogeneous modification procedures, respectively. Their structures were characterized by FTIR, (13)C and (29)Si NMR spectroscopy. Surface morphologies and corresponding elemental composition were determined by using SEM and EDS techniques. The metal binding characteristics of the adsorbents towards Cu(2+) and Ni(2+) were studied in dilute aqueous solution which presents an interesting aspect of increasing trend. (C) 2009 Elsevier B.V.
