Functionalized Carbon Nanotubes Produced by APCVD using Camphor
A simple chemical vapor deposition technique at atmospheric pressure (APCVD) is adopted to synthesize the aligned arrays of functionalized multi-walled carbon nanotubes (AMWCNTs) without using any carrier gas, at 230◦C, 750◦C and 850 ◦C. Camphor (C10H16O) is used as carbon source because this botanical hydrocarbon is chip and abundant which convert the CVD technique to a green method for produc...
متن کاملEthylbenzene 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...
متن کاملthermodynamic analysis of reactive red 198 removal from synthetic wastewater by using multiwall carbon nanotubes
conclusions the study results showed that by increasing the initial dye concentration and contact time, the adsorption capacity increased, as well. moreover, the thermodynamic parameters (δh °, δg °, and δs °) revealed the endothermic sorption of rr-198 onto mwcnts. results the rr-198 absorption rates were 33.26 and 222.88 mg/g, respectively for 20, and 200 mg/l dye concentration, at ph of 3, 6...
متن کاملRemoval of caffeine from aqueous solution using multi-wall carbon nanotubes: kinetic, isotherm, and thermodynamics studies
The occurrence of contaminants in wastewaters, and their behavior during wastewater treatment and production of drinking water are key issues to re-use water resources. The present research aims to remove caffeine from aqueous solutions via adsorption technique, using Multi-Wall Carbon Nanotubes (MWCNTs) as an adsorbent under different experimental conditions. The processing variables such as p...
