Then using of strong oxidants, such as HNO3 and HCl, is applied to oxidize CNTs to form carboxylic acid group and hydroxyl group. The silver nanoparticles will be deposited onto the modified CNTs. The physical properties and structural information were characterized by TGA, XRD, TEM and FT-IR. Finally, the (Ag/CNT) efficiency studied using E. coli. The nanoscale and well-dispersed a silver nanoparticles on the CNT can be obtained due to the carbon nanotubes with HNO3 treatment. In addition, the sample in the density 5 mg/ml has close on 100% efficiency and the (Ag/CNT) load in 10 wt% possesses the highest efficiency of E. coli test. The results of TEM, we prove the nano-particles and dispersity can enhance the efficiency of the (Ag/CNT) in E coli test.
