METHOD FOR EXTRACTING NANOPARTICLE

摘要

PROBLEM TO BE SOLVED: To extract a relatively large amount of nanoparticles in a relatively short time by carrying out both a mixing and extracting process and a separating process simultaneously and continuously. SOLUTION: The method for extracting nanoparticles includes the mixing and extracting process of extracting nanoparticles from one solvent to another solvent by adding both the other solvent composed of an aqueous solvent or a nonaqueous solvent and a dispersing agent having an affinity with the other solvent to a nanoparticle dispersed liquid where nanoparticles are dispersed in one solvent composed of an aqueous solvent or a nonaqueous solvent and by mixing them, and the separating process of separating one solvent from the other solvent from which nanoparticles are extracted. The mixing and extracting process and the separating process are continuously carried out by successively flowing a mixed solution containing one solvent and the other solvent mixed in a solvent mixing part 11 to a separating part 12 through using a device 10 having the solvent mixing part 11 performing the mixing and extracting process and the separating part 12 performing the separating process.
