![]() ![]() Thermodynamic parameters values showed that the adsorption of ions on SWCNT-COOH and SWCNTs at 283–313 K is spontaneous and endothermic. Recent work has produced non-planar carbon-based nanostructures such as fullerenes, carbon pyramids, and buckybowls from their corresponding quasi-planar polycyclic aromatic hydrocarbon. Maximum adsorption capacities (qm) for Pb(II), Cu(II) and Cd(II) ions onto SWCNT-COOH were obtained as 96.02, 77.00 and 55.89 mg/g, respectively, and by SWCNTs as 33.55, 24.29 and 24.07 mg/g, respectively. The results also demonstrated that SWCNT-COOH surfaces can more effectively adsorb mentioned ions than a SWCNT surface. The results indicated that Langmuir model fits adsorption isotherm data better than the Freundlich model. The effect of contact time, pH, initial concentration of ion, ionic strength and temperature on the adsorption of ion was investigated. read more read lessĪbstract: The equilibrium and thermodynamics of Pb(II), Cd(II) and Cu(II) ions adsorption from aqueous solution onto single-walled carbon nanotube (SWCNT) and carboxylate group functionalized single-walled carbon nanotube (SWCNT-COOH) surfaces were studied by atomic absorption spectroscopy. Based on experimental data shown in this work Ag nanoparticles with smaller sizes (3.04 ± 0.64 nm) and narrower size range (2–6 nm, approximately % 90) that homogenously deposited on graphene nanosheets were obtained by simultaneous reduction method, compared to sequential. The structure and morphology of the prepared nanocomposites were characterized with Fourier transform infrared spectrophotometer (FTIR), UV-visible spectra, scanning electron microscope (SEM), transmission electron microscope (TEM), and Raman spectra. Since their discovery about 10 years ago, researchers have extensively. The effect of synthesis parameters such as AgNO3 amount, concentration of AgNO3 solution, reducing agent amount, concentration of reducing agent solution, on the mean size and particle size distribution of Ag nanoparticles deposited on graphene nanosheets were examined. Nanotubes are large, linear fullerenes with aspect ratios as large as 10 3 to 10 5. Roberts, and J.N.Abstract: Graphene/Ag nanocomposites were prepared with two different approaches (i) sequential reduction of graphene oxide and silver nitrate (AgNO3), (ii) simultaneous reduction of graphene oxide and AgNO3 with hydrazine hydrate.
