Abstract

The invention discloses a chitosan bonded organic-silica gel hybridization monolithic column and a preparation method thereof. The chitosan bonded organic-silica gel hybridization monolithic column is prepared by combining the following components in percentage by mass with chitosan: 24% of a functional monomer with an amide group, 6% of a cage-like polysilsesquioxane cross-linking agent, 1.0% of an initiator and 69.0% of a pore-foaming agent. The invention further provides a preparation method of the chitosan bonded organic-silica gel hybridization monolithic column. The chitosan bonded organic-silica gel hybridization monolithic column disclosed by the invention has a nano cage-like siloxane structure, and is high in specific surface function and biocompatibility, and rich in hydroxyl and amino due to post-column bonded chitosan so as to provide abundant hydrogen bonds and perform hydrophilic interaction, thereby being applicable to analysis and separation of carbohydrates such as monosaccharide and disaccharide with high hydrophilcity.

Description

technical field

[0001] The invention relates to the field of chemistry, in particular to a chitosan-bonded organic-silica gel hybrid integral column and a preparation method thereof. Background technique

[0002] Sugar is the main carbohydrate in raw milk. Sugars such as monosaccharides and disaccharides play an important role in the formation of the nervous system, skin texture, and bones. For example, digested lactose can promote the formation of cerebrosides and mucopolysaccharides. Generation is crucial for the development of the infant brain. The quality control of carbohydrates in raw milk and dairy products is of great significance.

[0003] At present, the determination methods of sugars such as monosaccharides and disaccharides mainly include enzymatic method, direct titration method, direct colorimetric method, near-infrared spectroscopy, optical rotation method, high performance liquid chromatography, capillary electrophoresis, etc. The chemical analysis method ...
