ABSTRACT:
Disclosed herein is a nano-powder extraction apparatus using the rotation of a hollow impeller, which is configured to extract nano-powder according to particle size thereof by effectively dissolving the nano-powder contained in plasma gas into a surfactant solution, and to prevent the aggregation of nano-powder as the nano-powder is absorbed in and collected by a surfactant of solution, thereby enabling the application of strongly reactive materials.
