    Abstract: Solutions of carbon nanotubes and methods for purifying the solutions are provided. The methods include mixing, for example, at least one complexing agents, at least one ionic species, and/or at least one buffer oxide etch (BOE) with a liquid medium containing carbon nanotubes and different types of contaminants, such as metal impurities, amorphous carbon, and/or silica particles, and performing a filtration process to the liquid medium so as to remove or reduce the contaminants in the liquid medium. As a result, carbon nanotube solutions of low contaminants are produced. In some embodiments, the solutions of this disclosure include a high concentration of carbon nanotubes and are substantially free from metal, amorphous carbon, and/or silica impurities.
