Study on the adsorption properties of an organic volatile contaminant on residual soil mixed with multi-walled carbon nanotube (MWNT) is presented. The soil samples were thoroughly characterized for their physical chemical properties and composition, particularly organic matter. The adsorption isotherms are well described by both Langmuir and Freundlich models. The result shows that MWNT can be good...
In this work, homogeneous dispersion of multiwall carbon nanotubes (MWCNTs) in the hydrophilic polymer poly (vinyl)alcohol (PVA) in the presence of organic surfactant sodium dodecyl sulfate (SDS) was achieved. Further, thermal analysis shows that carbon nanotubes increase the glass transition temperature Tg and nucleate PVA crystallization. The observed results from Raman spectra recorded with 785...
Single-walled carbon nanotubes (SWNTs) are Introduced as a chemical sensor for the detection of sulfur dioxide (SO2) molecules. For a single bundle of SWNTs, current-voltage (I-V) curves were measured for a series of different temperatures under adsorption of SO2 molecules. The I-V characteristics for a "MAT"-type thin film SWNTs, with respect to the amount of SO2 adsorbed, were measured...
