Nobel Method for Toluene Removal from Air Based on Ionic Liquid Modified Nano-Graphen |
|
| چکیده انگلیسی مقاله |
The aim of this study was to investigate the removal of toluene from air through Nano-graphene modified by ionic liquid (NG-IL) . The batch adsorption experiments in glass bottle of gas chromatography equipped with flame ionization detector (GC-FID) were used. Graphene ultrahigh-quality synthesized by substrate-free gas-phase method in a single step and graphene sheets were deposited with ionic- liquid by thermal adsorption in acetone blank solution. Various conditions including contact time, amount of adsorbent , adsorbate concentration, humidity, and temperature were studied and optimized. NG-IL adsorbent was used for the adsorption of toluene vapor from gaseous media and the effect of different conditions such as; toluene concentration, humidity, and temperature on the adsorption were investigated. The Langmuir adsorption isotherms were employed for toluene by NG-IL adsorbent. The adsorption capacity was decreased by raising the sorbent humidity above of 50 percent. The toluene capture capacity for NG-IL was 126 mg/g . The results of SEM, XRD and TEM showed that the NG-IL have beneficial surfaces for toluene removal. NG-IL as a novel adsorbent has not previously been used for the adsorption of pollutants. |
