In this paper, a hybrid monolithic column with modified nanodiamond and 1-dodecene as co-monomers was prepared and applied to the online enrichment and purification of β-sitosterol in edible oil. The obtained monolithic column was characterized by scanning electron microscopy (SEM) and nitrogen adsorption–desorption isotherm measurement, which indicated that the monolith possessed characteristics...
A nanodiamond-based composite monolithic column was fabricated by redox initiation for high performance liquid chromatography (HPLC). The functionalized nanodiamond was modified via Fenton Reagent and 3-methacryl oxypropyltrimethoxysilane (KH-570). After being optimized conditions, composite monolithic columns were prepared with functionalized ND (f-ND) as functional monomer, dipentaerythritol hexaacrylate...
A nanodiamond-polymer composite monolithic column was first prepared successfully with modified nanodiamond (ND) as monomer, ethylene glycol dimethacrylate (EDMA) as cross-linker, 1-dodecanol as porogenic agent and benzoyl peroxide/dimethylacetamide (BPO/DMA) as initiator at 35°C for 2.5h. There was a sharp increase of specific surface area with ND added about 22 times from 0mg (3.90m2/g) to 7mg (81...
