Melamine Sponge Functionalized with Urea-Formaldehyde Co-Oligomers as a Sorbent for the Solid-Phase Extraction of Hydrophobic Analytes
García-Valverde, María Teresa; Chatzimitakos, Theodoros; Lucena, Rafael; Cárdenas, Soledad; Stalikas, Constantine D. (MDPI, 2018)A new procedure for the functionalization ofmelamine sponge (MeS) with urea-formaldehyde (UF) co-oligomers is put forward. The procedure differs from the typical synthesis of the UF co-polymer, as it employs a base-catalyzed ...
