Epub 2009 Apr 23.Nanoporous silica (SBA-15) was prepared and functionalized with 3-[Bis(2-hydroxyethyl)amino] propyl-triethoxysilane (HPTES) to be used as a highly porous fiber coating material for solid-phase microextraction (SPME). The prepared HPTES-SBA-15 particles had a lengthy morphology and a specific surface area of 790 m(2) g(-1). They were characterized by N(2) sorption analyses, scanning electron microscopy and thermogravimetric analysis. Read More
