Nanostructured carbon materials in water sterilization/purification.

摘要

This paper describes methods used to overcome the problems of removing bacteria and other organisms from water. One method includes removing the pathogens by filtration (size exclusion of bacteria) using a device with carbon nanotubes, and the other approach exploits the bactericidal property of silver nanowires (AgNWs) and uses a three-component system (vide infra) which inactivates bacteria. The paper also describes the use of an inexpensive material like graphite oxide as an adsorbent to remove heavy metal ions like mercuric ion and dyes.
