Firstly, XRD, TEM and FT-IR were used to characterize the structure of CNTs treated by dense HC1, dense HNO_3, HNO_3, H_2SO_4-HNO_3, K_2Cr_2O_7-H_2SO_4 and bromic acid. The results showed that purification treatment had no change on the structure of CNTs. But on the top of CNTs have function group such as -OH and -COOH after H_2SO_4-HNO_3 and K_2Cr_2O_7-H_2SO_4 were treated.
