Abstract: After being purified with the mixture of sulfuric acid and nitric acid,the carbon nanotubes(CNTs) were dispersed in aqueous solution with various surfactants by ultrasonic agitation.Then the dispersity was evaluated with settlement time.The experimental rersults show that the carbon nanotubes disperse very well in the HTAB or OP emulsifying agent with an appropriate concentration.

Key words: multi-walled carbon nanotubes（MWNTs）; purification; surface active agent; dispersion;
