Abstract: A nanocarbon separation apparatus includes: an electrophoresis tank; electrodes disposed in an upper part and a lower part of the electrophoresis tank; a first injection port through which a liquid is injected into the electrophoresis tank; a second injection port which is provided below the first injection port and through which a liquid having a pH lower than a pH of the liquid injected through the first injection port is injected into the electrophoresis tank; and a recovery port provided in a surface facing a surface having the first injection port and the second injection port, wherein the liquid injected through at least one of the first injection port and the second injection port is a dispersion liquid having nanocarbons dispersed therein.

Abstract: A nanocarbon separation method includes: a step of preparing a plurality of liquids with different specific gravities in which at least one of the plurality of liquids is a dispersion liquid in which a mixture of nanocarbons with different properties is dispersed; a step of sequentially injecting the plurality of liquids into an electrophoresis tank so that the specific gravities of the liquids decrease from a bottom to a top of the liquids in a direction of gravitational force; and a step of separating the mixture of the nanocarbons by moving a part of the mixture toward an electrode side disposed in an upper part of the electrophoresis tank and moving a remainder of the mixture toward an electrode side disposed in a lower part of the electrophoresis tank by applying a direct current voltage to the electrodes.
