Inverse gas chromatography as a tool for investigation of nanomaterials
چکیده انگلیسی

Inverse gas chromatography (IGC) is presented as a representative tool for the investigation of nanomaterials: Aerosil200V and two iron oxides (nanohematite and nanogoethite). IGC was used for characterization of the surface properties of materials. Parameters describing their surface properties are calculated from the retention data of test solutes injected into a column filled with the solid of interest. It is possible to determine the surface activity and the Hamaker constants of different nanomaterials.

Hamaker constant may be determined by inverse gas chromatography. It is shown that the use of constant value of Hamaker parameter in simulation procedures in disperse system cannot be advised.Figure optionsDownload as PowerPoint slide
