Adsorption of Humic Acid On Multi-Walled Carbon Nanotubes
Background: Natural organic matters (NOMs) have the main role in formation of trihalomethanes. These compounds are in natural water sources due to biological activities. In the presented study, adsorption and separation of humic acid as an index of natural organic matters using multi-walled carbon nanotubes is evaluated. Methods: The experiments were carried out in bath adsorption reactors wit...
متن کاملAscorbic acid determination using a carbon paste electrode modified with iron(III) ions adsorbed on humic acid
An amperometric sensor was constructed, by using humic acids to immobilize Fe3+ ions on a carbon paste electrode (CPE-HA-Fe), and used for ascorbic acid (H2A) determination. The cyclic voltammogram of the electrode showed electrochemical response due to the Fe3+/Fe2+ couple at E1/2=+0.78 V vs SCE, using 0.5 mol L-1 KCl and 0.2 mol L-1 acetate/0.020 mol L-1 phosphate buffer, at pH = 5.4, as supp...
متن کاملFabrication of carbon nano-tubes decorated with ultra fine superparamagnetic nano-particles under continuous flow conditions.
Ultra fine (2-3 nm) magnetite (Fe(3)O(4)) nano-particles are uniformly deposited on single-walled carbon nano-tubes (SWCNTs) pre-functionalised with carboxylic acid groups using microwave radiation. The deposition process involves chemical precipitation associated with continuous flow spinning disc processing (SDP), as a rapid, environmentally friendly approach which is readily scalable for lar...
متن کاملKinetics of subsurface hydrogen adsorbed on niobium: Thermal desorption studies
The adsorption/absorption of hydrogen and the adsorption of carbon monoxide by niobium foils, at room temperature, was studied using thermal desorption spectroscopy. Two hydrogen desorption peaks were observed with a maximum at 404 and 471 K. The first hydrogen desorption peak is regarded as hydrogen desorbing from surface sites while the second peak, which represents desorption from surface si...
متن کاملA review on Carbon nano-tubes - A new era of nanotechnology
Carbon nanotubes, which consist of rolled graphene sheets built from sp hybridized carbon atoms, were reported to be discovered in 1991, and are now attracting researchers from various disciplines due to their alluring physico-chemical properties. The special nature of carbon combines with the molecular perfection of buckytubes to endow them with exceptionally high material properties such as e...
