Effect of the graphite surface charge on the orientation of nitroalkane molecules in an adsorption layer
- 44 Downloads
Measurements have been made of electroosmotic transport of aqueous phosphate nitroalkane solutions through oxidized and unoxidized high-purity graphite diaphragms.
The variation of the electroosmotic transport with the molecular weight of the adsorbed compound is such as to indicate that the nitroalkane molecule is preferentially normally oriented with respect to the oxidized surface, and preferentially tangentially oriented with respect to the unoxidized surface.
