提纯

Since the production of carbon nanotubes synthesized by arc-discharge method contains impurities such as carbon nano-particles, amorphism carbon and graphite fragment, several purification methods were used to purify carbon nanotubes. It is found that with oxidation method in air, we can easily get purified carbon nanotubes.
