摘要：

Highly ordered carbon nanotubes arrays produced within pores of nano porous anodic alumina template via chemical vapor deposition method and pyrolysis of ethylene gas. Effective removal of copper (II) and cadmium (II) from simulated industrial waste water was performed with the nanometer scale pores in composite membrane of highly ordered carbon nanotubes. Our results shows that hydrophobic inner walls of carbon nanotubes have capability to adsorb heavy metal ions. Water pH effect on removal efficiency of composite membrane in was also investigated and the results showed that adsorption percentage of ions is enhancing with increasing pH of the solutions.
