Characterization of Multiwalled Carbon Nanotubes Dispersing in Water and Association with Biological Effects
Figure 6
UV spectroscopy of MWCNTs, in which (a) is UV spectra of as-received MWCNTs with different average lengths, (b) is UV spectra of the four kinds of oxidized l-MWCNTs, (c) presents representative spectra of MWCNTs containing three resolved peaks, and (d) and (e) display the relation of intensity and wavelength of peak 2 with as-received MWCNTs and oxidized MWCNTs, respectively.
