Description

Technical Field

[0001] The present invention relates to the field of purification technology, and more specifically, to a stearate purification method and system based on solid phase extraction technology. Background Art

[0002] Solid phase extraction technology is a sample pretreatment method based on chromatography theory. It uses the principles of selective adsorption and selective elution to enrich, separate and purify the target in the sample. Compared with the traditional liquid-liquid extraction method, solid phase extraction has the advantages of strong selectivity, short separation time, high recovery rate, non-emulsification, low organic solvent usage and easy automation.

[0003] In the purification process of stearate, solid phase extraction technology can effectively separate stearate from complex matrices and remove impurities, thereby improving purification efficiency and product quality. Specifically, solid phase extraction technology can achieve purification by selecting suitable adsorbents (such as silica gel, alumina, etc.) and eluents, adsorbing stearate on the adsorbent, and then desorbing stearate from the adsorbent through the elution process.
