| titleOfInvention | Silica gel chromatography packing and preparation method thereof |
| abstract | The invention provides a preparation method of zwitterionic hydrophilic silica gel chromatography packing. The preparation method comprises the following steps that (1) silica gel is subjected to activation pretreatment to prepare activated silica gel; (2) the activated silica gel is subjected to epoxidation modification to prepare epoxy modified silica gel; (3) tertiary amido is introduced onto the epoxy modified silica gel to prepare tertiary amido modified silica gel; and (4) sulfo is introduced onto the tertiary amido modified silica gel to prepare the zwitterionic hydrophilic silica gel chromatography packing. The prepared silica gel chromatography packing is small in electrostatic interaction and has a good absorption effect on an ionic or polar target object. |
