Cyclodextrin modified gold nanoparticles-based open-tubular capillary electrochromatographic separations of polyaromatic hydrocarbons
Original language description
In this study, spherical gold nanoparticles (GNPs) of 14.7 nm diameter, prepared by citrate reduction of a gold(III) salt and characterized by UV-Vis absorption spectrometry and transmission electron microscopy, were modified by a covalent attachment of6I-O-(3-mercaptopropyl)?-cyclodextrin (?-CD-SH) or per-6-deoxy-per-6-mercapto-?-cyclodextrin (?-CD-SH7). Subsequently, via three alternative approaches, ?-CD-modified GNPs were immobilized onto the inner wall of the fused-silica (FS) capillaries and applied as special stationary phases for open-tubular capillary electrochromatography (OT-CEC). The first immobilization procedure was based on pre-derivatization of a FS capillary with (3-mercaptopropyl)trimethoxysilane (MPTMS) followed by subsequent reactions with GNPs and ?-CD-SH or ?-CD-SH7. The other two preparation protocols took advantage of sol-gel approach gaining a significant increase in the interaction surface for solutes.
