solid phase extraction of some lanthanide ions by functionalized sba-15 fromenvironmental samples
in this research, nanoporous silica (sba-15) was physically functionalized using2-(2-nitrobenzylideneamino) guanidine compound. this functionalized sba-15 was utilized as a new sorbentfor separation and preconcentration of some lanthanide ions. inductively coupled plasma optical emissionspectrometry (icp-oes) was used as a detection technique. the preconcentration factor of the method is 100and...
متن کاملChemically Modified Eggshell Membrane as an Adsorbent for Solid-Phase-Extraction of Morphine Followed by High Performance Liquid Chromatography Analysis
In this project, eggshell membrane was used as a solid phase extraction sorbent for extraction of morphine followed by HPLC analysis. At first, raw eggshell membrane was used and then, because of low adsorption of morphine on untreated eggshell membrane (<70%), modification of eggshell membrane surface was carried out using different surfactants and amines. The amine modified eggshells characte...
متن کاملCeO2-modified Au@SBA-15 nanocatalysts for liquid-phase selective oxidation of benzyl alcohol.
Tuning the interfacial perimeter and structure is crucial to understanding the origin of catalytic performance. This paper describes the design, characterization, and application of CeO2 modified Au@SBA-15 (Au-CeO2@SBA-15) catalysts in selective oxidation of benzyl alcohol. The reaction results showed that Au-CeO2@SBA-15 catalysts exhibited higher catalytic activity compared with Au@SBA-15 and ...
متن کاملSelective Preparation of Furfural from Xylose over Sulfonic Acid Functionalized Mesoporous Sba-15 Materials
Sulfonic acid functionalized mesoporous SBA-15 materials were prepared using the co-condensation and grafting methods, respectively, and their catalytic performance in the dehydration of xylose to furfural was examined. SBA-15-SO3H(C) prepared by the co-condensation method showed 92–95% xylose conversion and 74% furfural selectivity, and 68–70% furfural yield under the given reaction conditions...
