Because of their persistence and wide distribution removal from the environment is an important challenge. Here we report a new Nano container matrix based on the deep sea archaea-derived RHCC-Nanotube (RHCC-NT), which rapidly and preferentially binds low molecular weight PAHs. Under controlled-laboratory conditions and using fluorescence spectroscopy in combination with X-ray crystallography and MD simulations, we quantified the real-time binding of low molecular weight PAHs (2-4 rings) to our substrate. Binding coefficients ranged from 5.4 +/- 1.6 (fluorene) to 32 +/- 7.0 muM (acenaphthylene) and a binding capacity of 85 pmoles PAH per mg RHCC-NT, or 2.12 mumoles in a standard 25 mg sampler. The uptake rate of pyrene was calculated to be 1.59 nmol/hrmol RHCC-NT (at 10 C). Our results clearly show that RHCC-NT is uniquely suited as a monitoring matrix for low molecular weight PAHs.
