|Title:||Diffusive Transport of Multiwall carbon nanotubes through an HDPE geomembrane|
|Published:||September 30, 2013|
|Abstract:||Carbon nanotubes are used in a wide range of consumer products. During the last few years, the applications for, and production of, carbon nanotubes has increased substantially. Due to their potential environmental and human health risks and eventual disposal into landfills, understanding their mobility through landfill's barrier system is essential. The diffusion of multiwall carbon nanotubes (MWCNTs) through a 0.5 mm high density polyethylene (HDPE) geomembrane is examined in this study. The preliminary results from two-compartment diffusion cells show no significant partitioning of MWCNTs from source to geomembrane or diffusion of MWCNT during the testing period reported. This is the first time the potential migration of nanoparticles through a geomembrane has been examined. These tests are on-going and the most recent results will be presented at the conference.|
