Title:
SOLVENT SUBSTITUTION-BASED MAGNETIC SOLID-PHASE EXTRACTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/193861
Kind Code:
A1
Abstract:
A magnetic solid-phase extraction method for improving the adsorption rate of a magnetic solid-phase extraction material by means of solvent substitution. A solvent in an extraction solution containing a target is substituted with a poor solvent of the target to change a partition coefficient of the target in the extraction solution and a solid phase, so that the partition coefficient of the target in the extraction solution is reduced, an extraction equilibrium tips to the solid phase, and the adsorption rate of the solid phase for the target is improved. The method is applicable to extraction of trace targets.
