Comparative Study of Isotherms Adsorption of Oleic Acid by Activated Carbon and Multi-wall Carbon Nanotube
This experimental study aimed to compare the adsorption of oleic acid (fatty acid) by two adsorbent; activated carbon and carbon nanotube by use of Uv-Vis spectrophotometer Jenway 6505 model. In this study, five different concentrations of oleic acid in the range of 282.47ppm to 847.41ppm were used. In all conducted experiments, the values of adsorbents, exposure time, temperature, and pH were ...
متن کاملLow pressure adsorption of CO2 on multi-wall carbon nanotubes
Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...
متن کاملCO2 adsorption on the surface and open ended of Single wall carbon nanotubes (SWCNTs): A Comparative study
Adsorption of CO2 on the surface of Single-wall zigzag (5,0) and armchair (4,4) carbon nanotubes (SWCNTs) were studied through using density functional theory (DFT) calculations. Optimizations of geometric were performed at the B3PW91 level of 6-311++G** method standard basis set using GAUSSIAN 03 package of program [1]. Structural models were optimized and adsorption energies, band gap, charge...

متن کاملComparative Study of Adsorption Isotherms Steroidal Anti-Inflammatory Drug Dexamethasone on Carbon Nanotube and Activated Carbon
In this research we have studied aimed to compare the adsorption of dexamethasone by two adsorbent; multi-wall carbon nanotube and activated carbon with the help of UV/VIS spectrophotometer Jenway 6505 model. Adsorption chart based on the wavelength of dexamethasone has been obtained and the relevant graph is plotted by considering factor of concentration. Four different concentrations necessar...
