| titleOfInvention | Ultrasonic reflux system for one-step purification of carbon nanostructures |
| abstract | A reflux system including a solvent flask, an extraction tube connected to the solvent flask by a siphon tube and a vapor tube each extending between the extraction tube and the solvent flask, and an energy applicator disposed around the bottom portion of the extraction tube. Further, a condenser is connected to the top portion of the extraction tube. A supply tube is connected to the extraction tube, whereby material can be introduced into the extraction tube. The reflux system is used in a one-step method, of purifying carbon nanostructures, including placing a soot sample?containing the carbon nanostructures and amorphous carbon?in a filter and disposing the filter in the extraction tube. Solvent is then introduced into the extraction tube so as to collect in the lower portion thereof, and remove one of the amorphous carbon and the carbon nanostructures from the soot. Further, the energy applicator is used to apply ultrasonic vibrations to the soot so as to disperse agglomerations therein. The solvent, and the one of the amorphous carbon and carbon nanostructures dissolved therein, is then removed from the extraction tube so that the other one of the amorphous carbon and the carbon nanostructures remains in the filter. Further, the method is performed at ambient temperature, an oxidizing gas is introduced into the extraction tube to oxidize the amorphous carbon, and acid is introduced into the extraction tube to remove metallic particles from the soot. |
