Title:
FINE PARTICLE ADSORPTION MATERIAL AND FINE PARTICLE REMOVAL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/254873
Kind Code:
A1
Abstract:
Provided are a fine particle adsorption material and removal method that enable sufficient removal of fine particles from a solvent having a low water content. This fine particle adsorption material is for adsorbing and removing fine particles from a solvent containing the fine particles. The material has a graft chain that is a negatively charged group. A polymer material that serves as a base material for the fine particle adsorption material is an aliphatic hydrocarbon, or an aliphatic hydrocarbon containing fluorine or chlorine. This method for removing fine particles from a solvent comprises bringing said fine particle adsorption material into contact with the solvent, and thereby causing the fine particles in the solvent to be adsorbed by the fine particle adsorption material and to be removed from the solvent.
