Abstract: AbstractA gold(III)-imprinted thiocyanato-functionalized silica network of type SBA-15 was prepared by co-condensation of tetraethoxysilane (TEOS) with thiocyanatopropyltriethoxysilane (TCTES) in the presence of Pluronic123 and Au(III) ions. Compared to the non-imprinted material, the imprint has a…

Abstract: Abstract A typical l-cysteine functionalized magnetic mesoporous nanosorbent (Cys–Si–MNPs) was successfully synthesized and characterized by transmission electron microscopy, the nitrogen adsorption–desorption isotherm and X-ray photoelectron spectroscopy. The results showed that Fe3O4 magnetic core was shelled…
