Aqueous Solution Surface Chemistry of Carbon Nanotubes

Ethylbenzene Removal by Carbon Nanotubes from Aqueous Solution

The removal of ethylbenzene (E) from aqueous solution by multiwalled, single-walled, and hybrid carbon nanotubes (MWCNTs, SWCNTs, and HCNTs) was evaluated for a nanomaterial dose of 1 g/L, concentration of 10-100 mg/L, and pH 7. The equilibrium amount removed by SWCNTs (E: 9.98 mg/g) was higher than by MWCNTs and HCNTs. Ethylbenzene has a higher adsorption tendency on CNTs, so that more than 98...

Acid violet 17 Dye Decolorization by Multi-walled Carbon Nanotubes from Aqueous Solution

Background: Dyes can cause many problems in environment. Therefore, removal of these contaminants before discharging wastewater to environment can reduce the environmental hazards. Adsorption is one of the usual processes for decolorizing from wastewater. Nanotubes are new adsorbents that can adsorb different compounds. This work aimed to investigate Acid violet 17 dye removal by adsorption usi...

Carbon dioxide reduction by mononuclear ruthenium polypyridyl complexes.

New mononuclear ruthenium complexes with general formula [Ru(bid)(B)(Cl)] (bid is (1Z,3Z)-1,3-bis(pyridin-2-ylmethylene)isoindolin-2-ide; B = bidentate ligand 2,2'-bipyridine or R(2)-bpy, where R = COOEt or OMe) were synthesized and tested as precatalysts for the hydrogenative reduction of CO(2) in 2,2,2-trifluoroethanol (TFE) as solvent with added NEt(3). Significant amounts of formic acid wer...

Destabilization of Surfactant-Dispersed Carbon Nanotubes by Anions

The colloidal stability of surfactant-dispersed single-wall carbon nanotubes (SWCNTs) is determined by microscopic physicochemical processes, such as association, partitioning, and adsorption propensities. These processes can be controlled by the addition of solutes. While the effects of cations on the colloidal stability of SWCNTs are relatively well understood, little is known about the effec...
